Question

Alright, -3r + 4(-3r + 2) = 53 how do I break it down and solve??

Answer 1

r = -3

Explanation:

expand 4(-3r+2)

= -12r+8

add similar variables

= -15r+8=53

subtract 8 from both sides

= -15r+8-8=53-8

simplify

= -15r=45

divide 45 by -15

= -3

Answer 2

r = -3

Explanation:

-3r + 4(-3r +2) = 53

-3r + -12r + 8 = 53

-8 -8

-3r + -12r = 45

-15r = 45

Divide both sides by -15 to get

r = -3
