Question

Solve for m: -2/9m + 12 = -8

Answer 1

Explanation:

`\rm \rightharpoonup \: ( - 2)/(9)m + 12 = - 8 \\ \rm \rightharpoonup \: ( - 2)/(9) m = - 8 - 12 \\ \rm \rightharpoonup \: ( - 2)/(9) m = - 20 \\ \rm \rightharpoonup \: m = ( - 20 * 9)/( - 2) \\ \rm \rightharpoonup \: m = 10 * 9 \\ \rm \rightharpoonup \: m = 90`

Answer 2

90

Explanation:

−2/9m+12=−8

Step 1: Subtract 12 from both sides.

−2/9m+12−12=−8−12

−2/9m=−20

Step 2: Multiply both sides by 9/(-2).

(9/−2)*(−2/9m)=(9/−2)*(−20)

m=90
