7 - 5/2 (8r - 6) + 2r = 32

r = - 5/9

Step-by-step explanation:

distribute the 5/2 to the (8r - 6) so you get

7 - 20r + 15 + 2r = 32

combine like terms to get

-18r + 22 = 32

subtract 22 to both sides and you end up with

-18r = 10

divide both sides by - 18 and you end up with

r = - 0.5 repeating or - 5/9 as a simplified fraction
