Answer:
17) x = 0, -6
18) x = 2, -4
Step-by-step explanation:
Isolate the absolute value, then split into 2 equations and solve both
example: |x + 1| = 2
x + 1 = 2, x + 1 = -2
x = 1, -3
------------------------------------
17) |x + 3| - 1 = 2
isolate the absolute value:
|x + 3| = 3
x + 3 = 3, x + 3 = -3
x = 0, -6
-----------------------------------------
18) 3|x + 1| = 9
isolate absolute value:
|x + 1| = 3
x + 1 = 3, x + 1 = -3
x = 2, -4
