10-95.
Subtract 13 from both sides.
Square both sides.
x − 1 = 0
x = 1
Divide both sides by 6.
|x| > 3
Find the boundary point(s).
x = −3 or x = 3
Test x = −4, x = 0, and x = 4.
6|− 4| > 18 24 > 18 True
6|0| > 18 0 > 18 False
6|4| > 18 24 > 18 True
x < −3 or x > 3
3x − 2 = 2 or 3x − 2 = −2
Add 2 to both sides.
3x = 4 or 3x = 0
Multiply the equation by 30.
24 − 20x = 9
Subtract 24 from both sides.
−20x = −15
Divide by −20 on both sides and simplify.
