9) - 8 (m - 4) - 7 = 89

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
