The solution set is

Answer 1

Answer:

The solution set is {-27,21}

Step-by-step explanation:

lx-3l=24

There are two solutions to an absolute value equation, one positive and one negative.

x-3 = +24 and x-3 = -24

Add 3 to each side.

x-3-3 = +24-3 and x-3-3 = -24-3

x = 21           and x=-27

The solution set is {-27,21}
