Question

$$x+3x+4=84$$

Solve for x

$x=20$

Steps for Solving Linear Equation

Combine $x$ and $3x$ to get $4x$.

$$4x+4=84$$

Subtract $4$ from both sides.

$$4x=84-4$$

Subtract $4$ from $84$ to get $80$.

$$4x=80$$

Divide both sides by $4$.

$$x=\frac{80}{4}$$

Divide $80$ by $4$ to get $20$.

$$x=20$$
