Solve for r.

–16r + 15 + 17 = 7(–3r + 16) − 5r

r =

r = 8

Step-by-step explanation:

→Distribute the 7 to (-3r + 16):

-16r + 15 + 17 = 7(-3r + 16) - 5r

-16r + 15 + 17 = -21r + 112 - 5r

→Add like terms:

-16r + 32 = -26r + 112

→Add 26r to both sides:

10r + 32 = 112

→Subtract 32 from both sides:

10r = 80

→Divide both sides by 10:

r = 8

Step-by-step explanation:

-16r +15+17= 7(-3r+16)-5r

-16r+32 = -21r +112-5r

-16r +26r=112-32

10r =80

r=80/10

r=8
