\left(m-2\right)\times 3=m\times 4
Variable m cannot be equal to any of the values 0,2 since division by zero is not defined. Multiply both sides of the equation by m\left(m-2\right), the least common multiple of m,m-2.
3m-6=m\times 4
Use the distributive property to multiply m-2 by 3.
3m-6-m\times 4=0
Subtract m\times 4 from both sides.
-m-6=0
Combine 3m and -m\times 4 to get -m.
-m=6
Add 6 to both sides. Anything plus zero gives itself.
m=-6
Multiply both sides by -1.
