Step-by-step explanation:
[tex] \rm \rightharpoonup \: \frac{ - 2}{9}m + 12 = - 8 \\ \rm \rightharpoonup \: \frac{ - 2}{9} m = - 8 - 12 \\ \rm \rightharpoonup \: \frac{ - 2}{9} m = - 20 \\ \rm \rightharpoonup \: m = \frac{ - 20 \times 9}{ - 2} \\ \rm \rightharpoonup \: m = 10 \times 9 \\ \rm \rightharpoonup \: m = 90[/tex]
Answer:
90
−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
