Combine multiplied terms into a single fraction
-3/7m=12
-3m/7=12
Multiply all terms by the same value to eliminate fraction denominators
-3m/7=12
7x-3m/7=7x12
Cancel multiplied terms that are in the denominator
7x-3m/7=7x12
-3m=7x12
Multiply the numbers
-3=7x12
-3m=84
Divide both sides of the equation by the same term
-3m=84
-3m/-3=84/-3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
m=-28
