Answer:
Step-by-step explanation:
Given that,
-8(m – 4) – 7 = 89
We need to expand the bracket first
Also, note
-×-=+. -×+=- -÷+=- -÷-=+
Then,
-8(m – 4) – 7 = 89
(-8×m) (- 8×-4) - 7=89
-8m+32-7=89
-8m+25=89
Subtract 25 from both sides
-8m+25-25=89-25
-8m=64
Divide both sides by -8
-8m/-8=64/-8
m=-8
