Question

Solve for r. 12 = r - (34 - 2) Show your work!

Answer 1

Answer:

r = 44

Step-by-step explanation:

We need to find out the value of r that makes true that equation. For that, we need to leave the r alone in one side of the equation and get all the numbers together on the other side.

12 = r - (34 - 2)

First, let's resolve the calculation inside the parenthesis:

34 - 2 = 32

So,  

12 = r - 32

Now let's add 32 on both sides of the equation:

12 + 32 = r - 32 + 32

44 = r

Answer 2

The answer would be -20
