Answer 2
Answer:

1 ) n = -1/4

2 ) x = 3/5

Step-by-step explanation:

First equation:

1/2 = n + 3/4

Step 1 - Flip the equation:

n + 3/4 = 1/2

Step 2 - Subtract 3/4 from both sides:

n + 3/4 - 3/4 = 1/2 - 3/4 =

n = -1/4

Answer: n = -1/4

Second equation:

x - 1/2 = 1/10

Step 1 - Simplify both sides of the equation:

x + -1/2 = 1/10

Step 2 - Add 1/2 to both sides:

x + -1/2 + 1/2 = 1/10 + 1/2

x = 3/5

Answer: x = 3/5

Hope this could help!

Solve 15 = 1/3x
x = ?

Answers

Hey there!

The answer to your question is x = 45

To solve this, we want to get x with a coefficient of 1 by itself on one side of the equal sign, and right now it's coefficient is 1/3. We can get a coefficient of 1 by multiplying both sides of the equation by 3.

15(3) = 1/3x(3)

45 = x

Hope this helps and if you need any further help, I would be happy to!
