Question

8 + 2r = −10 what is r?

Answer 1

r=-9

Explanation:

Step 1:- Simplify both sides of the equation.

2r+8 = -10

Step 2:- For isolating the variable, subtract 8 from both sides.

2r+8-8 = -10-8

2r = -18

Step 3:- For isolating the variable, divide by 2 from both sides.

2r/2 =-18/2

r= -9

Hope this helps :)

Answer 2

r = -9

Explanation:

Subtract 8 from both sides to get 2r = -18. Divide by 2 on both sides to get r = -9.
