Solve for x 3x+wx=20

$3 x + w x = 20$

Step 1

Factor $x$ out of $3 x + w x$ .

Factor $x$ out of $3 x$ .

$x \cdot 3 + w x = 20$

Factor $x$ out of $w x$ .

$x \cdot 3 + x w = 20$

Factor $x$ out of $x \cdot 3 + x w$ .

$x (3 + w) = 20$

Step 2

Divide each term in $x (3 + w) = 20$ by $3 + w$ and simplify.

Divide each term in $x (3 + w) = 20$ by $3 + w$ .

$\frac{x (3 + w)}{3 + w} = \frac{20}{3 + w}$

Simplify the left side.

Cancel the common factor of $3 + w$ .

Cancel the common factor.

$\frac{x (3 + w)}{3 + w} = \frac{20}{3 + w}$

Divide $x$ by $1$ .

$x = \frac{20}{3 + w}$
