Question

$$3 x + 7 = x + 15$$

Solve for x

$x=4$

Steps for Solving Linear Equation

Subtract $x$ from both sides.

$$3x+7-x=15$$

Combine $3x$ and $-x$ to get $2x$.

$$2x+7=15$$

Subtract $7$ from both sides.

$$2x=15-7$$

Subtract $7$ from $15$ to get $8$.

$$2x=8$$

Divide both sides by $2$.

$$x=\frac{8}{2}$$

Divide $8$ by $2$ to get $4$.

$$x=4$$
