Answer:
m = -18
Step-by-step explanation:
-m/3 + 6 = 12
Subtract 6 from both sides
-m/3 = 6
we have to isolate x, to do that we use inverse operation
-m/3 = 6
multiply 3 on both sides of the equation
-m= 18
we can't leave the variable negative so we divide by -m on both sides to make the -m positive.
m= -18
