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!
