у= 4х + 3
у = -X - 2

Answers

Answer:

x = - 1

Step-by-step explanation:

y = 4x + 3

y = -x - 2

Find x:

4x + 3 = -x - 2

5x + 3 = - 2 (Adding x to both sides)

5x = - 5 (Subtracting 3 from both sides)

x = -1 (Dividing 5 from both sides)

Answer: x = - 1

What is the value of y?
What is the area, in square inches, of the rectangle

Answers

Answer:

Part A:  y = 3

Part B:  Area = 60 sq units

Step-by-step explanation:

we can create this system of equations from the information given:

10y + 2x = 40

now we can subtract to get:

-2y = -6

y = 3

solve for 'x':

24 + 2x = 34

2x = 10

x = 5
