-3(4r - 8) = -36
Mutiply the bracket by -3
(-3)(4r)(-3)(-8)= -12r+24
-12r+24= -36
move +24 to the other side
sign changes from +24 to -24
-12r+24-24= -36-24
-12r= -60
divide by -12
-12r/-12= -60/-12
r= 5
Answer: r= 5
Answer:
-3(4r-8)=-36
-3 ×4r = -12r
(Negative and positive equals negative)
-3×-8= 24
(Both negatives equal positive)
-12r+24=-36
(-24 to like terms. Meaning, just subtract 24 from the -36 and the 24
Leave change change uwo)
-36-(-24) is now -36 + 24= -12
-12/-12r= -12/-12
r=1
