Answer:

r = 1

Step-by-step explanation:

3(2x-2) - r + 3x=2(7x+1) - 5x - 9

First, use the distributive property to get rid of the parenthesis

After that, we would get,

6x - 6 - r + 3x = 14x + 2 - 5x - 9

Combine like terms

9x - 6 - r = 9x - 7

Minus 9x on both sides and plus 6 on both sides

-r = -1

r = 1

Hope this helps :)

Have a spectacular day!
