Answer
$x \leq -1$
Work Step by Step
Use the distributive property to simplify the left side of the equation:
$-12x + 3 \geq 15$
Subtract $3$ from each side of the inequality to isolate the constants on one side of the inequality:
$-12x \geq 12$
Divide each side by $-12$ to solve for $x$. When we divide by a negative number in an inequality, we switch the sign to the opposite sign:
$x \leq -1$
