Question

- 2(5-r) = 8 I need the solution

Answer 1

Distribute -2
-10+2r=8
Add 10 on both sides of the equal sign
2r=18
Divide both sides of the equal sign by 2
r=9

Answer 2

Answer: r = 9

Explanation:

In order to find r, isolate it on one side.

Given equation:

-2(5 - r) = 8

Distribute -2:

-10 + 2r = 8

2r = 8 + 10

2r = 18

r = 9
