Solve for x: 3|x − 3| + 2 = 14
vaieri [72.5K]

Answer:

x = 7                      x = -1

Step-by-step explanation:

3|x − 3| + 2 = 14

Subtract 2 from each side

3|x − 3| + 2 -2= 14-2

3|x − 3|  = 12

Divide by 3

3|x − 3| /3 = 12/3

|x − 3| = 4

Now the absolute value has a positive and negative solution.

x-3 = 4      x-3 = -4

Add 3 to each side

x-3+3 = 4+3      x-3+3 = -4+3

x = 7                      x = -1
