5-90.

Solve each equation or inequality.

1. $|x-1|=9$

Rewrite the equation as: $x−1=9$ or $x−1=−9$

Solve and check both equations.

1. $2|x+1|+3=9$

Get the absolute value expression by itself first. Then rewrite the equation using the hint in part (a).

1. $|x-1|<3$

$−2

1. $|x+5|\ge8$

See part (c).
