5m+2=2\left(m-2\right)
Variable m cannot be equal to 2 since division by zero is not defined. Multiply both sides of the equation by m-2.
5m+2=2m-4
Use the distributive property to multiply 2 by m-2.
5m+2-2m=-4
Subtract 2m from both sides.
3m+2=-4
Combine 5m and -2m to get 3m.
3m=-4-2
Subtract 2 from both sides.
3m=-6
Subtract 2 from -4 to get -6.
m=\frac{-6}{3}
Divide both sides by 3.
m=-2
Divide -6 by 3 to get -2.
