Solve for m 9m-4=-18+2m

$9 m - 4 = - 18 + 2 m$

Step 1

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

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

$9 m - 4 - 2 m = - 18$

Subtract $2 m$ from $9 m$ .

$7 m - 4 = - 18$

Step 2

Move all terms not containing $m$ to the right side of the equation.

Add $4$ to both sides of the equation.

$7 m = - 18 + 4$

Add $- 18$ and $4$ .

$7 m = - 14$

Step 3

Divide each term in $7 m = - 14$ by $7$ and simplify.

Divide each term in $7 m = - 14$ by $7$ .

$\frac{7 m}{7} = \frac{- 14}{7}$

Simplify the left side.

Cancel the common factor of $7$ .

Cancel the common factor.

$\frac{7 m}{7} = \frac{- 14}{7}$

Divide $m$ by $1$ .

$m = \frac{- 14}{7}$

Simplify the right side.

Divide $- 14$ by $7$ .

$m = - 2$
