Question

$$-3(2x+1)=21$$

Solve for x

$x=-4$

Steps for Solving Linear Equation

Divide both sides by $-3$.

$$2x+1=\frac{21}{-3}$$

Divide $21$ by $-3$ to get $-7$.

$$2x+1=-7$$

Subtract $1$ from both sides.

$$2x=-7-1$$

Subtract $1$ from $-7$ to get $-8$.

$$2x=-8$$

Divide both sides by $2$.

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

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

$$x=-4$$
