Question

$$9x+12=120-9x+18$$

Solve for x

$x=7$

Steps for Solving Linear Equation

Add $120$ and $18$ to get $138$.

$$9x+12=138-9x$$

Add $9x$ to both sides.

$$9x+12+9x=138$$

Combine $9x$ and $9x$ to get $18x$.

$$18x+12=138$$

Subtract $12$ from both sides.

$$18x=138-12$$

Subtract $12$ from $138$ to get $126$.

$$18x=126$$

Divide both sides by $18$.

$$x=\frac{126}{18}$$

Divide $126$ by $18$ to get $7$.

$$x=7$$
