$$x = -5$$

Work Step by Step

To solve this equation, we want to move the constants to one side of the equation and keep the variable on the other side. For this equation, we want to add $7$ to each side of the equation: $$-3x = 8 + 7$$ $$-3x = 15$$ Divide each side by $-3$ to solve for $x$: $$x = -5$$
