Solve for m m-4=2m

$m - 4 = 2 m$

Step 1

Move all terms containing $m$ to the left side of the equation.

Subtract $2 m$ from both sides of the equation.

$m - 4 - 2 m = 0$

Subtract $2 m$ from $m$ .

$- m - 4 = 0$

Step 2

Add $4$ to both sides of the equation.

$- m = 4$

Step 3

Divide each term in $- m = 4$ by $- 1$ and simplify.

Divide each term in $- m = 4$ by $- 1$ .

$\frac{- m}{- 1} = \frac{4}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{m}{1} = \frac{4}{- 1}$

Divide $m$ by $1$ .

$m = \frac{4}{- 1}$

Simplify the right side.

Divide $4$ by $- 1$ .

$m = - 4$
