Solve for w -15-3w=4w-2w

$- 15 - 3 w = 4 w - 2 w$

Since $w$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$4 w - 2 w = - 15 - 3 w$

Subtract $2 w$ from $4 w$ .

$2 w = - 15 - 3 w$

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

Add $3 w$ to both sides of the equation.

$2 w + 3 w = - 15$

Add $2 w$ and $3 w$ .

$5 w = - 15$

Divide each term in $5 w = - 15$ by $5$ and simplify.

Divide each term in $5 w = - 15$ by $5$ .

$\frac{5 w}{5} = \frac{- 15}{5}$

Simplify the left side.

Cancel the common factor of $5$ .

Cancel the common factor.

$\frac{5 w}{5} = \frac{- 15}{5}$

Divide $w$ by $1$ .

$w = \frac{- 15}{5}$

Simplify the right side.

Divide $- 15$ by $5$ .

$w = - 3$
