Solve for x 5x+15+2x=24+4x

$5 x + 15 + 2 x = 24 + 4 x$

Step 1

Add $5 x$ and $2 x$ .

$7 x + 15 = 24 + 4 x$

Step 2

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

Subtract $4 x$ from both sides of the equation.

$7 x + 15 - 4 x = 24$

Subtract $4 x$ from $7 x$ .

$3 x + 15 = 24$

Step 3

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

Subtract $15$ from both sides of the equation.

$3 x = 24 - 15$

Subtract $15$ from $24$ .

$3 x = 9$

Step 4

Divide each term in $3 x = 9$ by $3$ and simplify.

Divide each term in $3 x = 9$ by $3$ .

$\frac{3 x}{3} = \frac{9}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} = \frac{9}{3}$

Divide $x$ by $1$ .

$x = \frac{9}{3}$

Simplify the right side.

Divide $9$ by $3$ .

$x = 3$
