Solve for x

x>-3

$x>−3$

Solution Steps

- 4 x + 60 < 72

$−4x+60<72$

Subtract 60 from both sides.

Subtract $60$ from both sides.

-4x<72-60

$−4x<72−60$

Subtract 60 from 72 to get 12.

Subtract $60$ from $72$ to get $12$.

-4x<12

$−4x<12$

Divide both sides by -4. Since -4 is <0, the inequality direction is changed.

Divide both sides by $−4$. Since $−4$ is $<0$, the inequality direction is changed.

x>\frac{12}{-4}

$x>−412 $

Divide 12 by -4 to get -3.

Divide $12$ by $−4$ to get $−3$.

x>-3

$x>−3$
