Answer:

17) x = 0, -6

18) x = 2, -4

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
