Question

1 2 - 5 ( 3 r + 2 ) = 1 7

Answer 1

Answer:r=1

Explanation:

12-5(3r+2)=17

Use PEMDAS

First step is

-5 *3r=-15r

-5*2=-10

Next you drag everything down

12-15r-10=17

Then you subtract terms

2-15r=17

Rerage terms

Next

-15r+2-2=17-2

-15r=17-2

Subtract terms

-15r=15

Divide -15 on both sides

r=-1
