Question

Solve each equation.
9) -8(m – 4) – 7 = 89

Answer 1

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
