Question

Solve for x: |2x + 6| − 4 = 20

Answer 1

Since it is an absolute value function, you must divide it into 2 parts, the first one is 2x+6 and the other one is -(2x+6). Solve the 2 equations right away and tell me your answer, i already got mine. :)

Answer 2

These are the choices
x = 9 and x = 11

x = −9 and x = 15

x = 9 and x = −15

No solution

Answer 3

|2x + 6| − 4 = 20
|2x + 6| =20+4
|2x + 6| =24
2x + 6=24 or 2x + 6=-24
2x=24-6 or 2x=-24-6
2x=18 or 2x=-30
x=18/2 or x=-30/2
x=9 or x=-15
