His mistake is that he does not open the bracket first. The value of the x is negative of 4.
What is a BODMAS rule?BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Andre tried to solve the equation 1/4 ( x + 12 ) = 2.
First, open the bracket, then we have
[tex]\dfrac{x}{4} + \dfrac{12}{4} = 2[/tex]
On simplifying, we have
[tex]\dfrac{x}{4 } + 3 = 2[/tex]
Subtract 3 from both sides, we have
[tex]\dfrac{x}{4} = -1[/tex]
Multiply the equation by 4, we have
[tex]x = -4[/tex]
More about the BODMAS rule link is given below.

1. The graph of y = f(x) is a parabola whose vertex is at (1, -2). The graph of y = f(x - 3) is also a parabola. Where is the vertex of the graph of y = f(x-3)? Write your answer as an ordered pair.
2. The graph of has the line as an axis of symmetry. The graph also passes through the point. Find another point that must lie on the graph of y = f(x).
3. The graph of y = f(x) is shown in the first picture in red. Find the equation that corresponds to the blue graph.
Enter your answer in the form "y = …".
4. The graph of y = h(x) is shown in red in the second picture. Compute h(h(7)).
(Assume grid lines are spaced 1 unit apart.)
5. In the third picture is a portion of the graph of a function, y=u(x):
What is the exact value of u(-2.72)+u(-0.81)+u(0.81)+u(2.72)?
Answer:
Q1The graph of y = f(x), has vertex at (1, -2)
The vertex of a function f(x - 3) is going to be:
(1 - 3, -2) = (-2, -2)Q2The graph of y = f(x) has the line x = 5 as an axis of symmetry. The graph also passes through the point (8,-7). Find another point that must lie on the graph of y = f(x).The axis of symmetry is at the same distance from the symmetric points.
x = 5 is a vertical line. The point (8, -7) is 3 units to the right. So the mirror point will be 3 units to the left and have same y-coordinate: x = 5 - 3 = 2
The point is (2, -7)
Q3The graph in blue is the translation of the red to the left by 2 units.
So the equation is:
y = f(x + 2)Q4y = h(x) is graphed
h(7) = 5h(h(7)) = h(5) = -1Q5The graph of the function y = u(x) given
This is a odd function.
The coordinates of u(x) and u(-x) add to zero because u(-x) = -u(x)
Therefore:
u(-2.72) + u(-0.81) + u(0.81) + u(2.72) = [u(-2.72) + u(2.72)] + [u(-0.81) + u(0.81)] = 0 + 0 = 0Simplify the fraction below.
35/4
Answer:
8 3/4
Step-by-step explanation:
find the greatest common factor of 35 and 4, which is 1. Then divide both 35 and 4 by the greatest common factor to get the following simplified fraction: 35/4
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. You could convert it into a whole number or mixed number fraction. Which would now be 8 3/4

6) Write a system of linear inequalities that is given by the following graph.
Answer:
The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be
⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)

Stuart wants to find the value of 3 3/4 -2 1/3 Before Stuart can subtract, he needs to rewrite both fractions with a common denominator. Drag a number or expression into each box to show how to write equivalent fractions so the new fractions have a common denominator.
Answer:
1 21/50
Step-by-step explanation:
3 3/4 = (3/4 x 4/4) = 3 9/12
2 1/3 = (1/3 x 3/3) = 2 4/12
3 9/12 - 2 4/12 = 1 21/50
