Answer:
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
