Question

Solve |2x – 6| = 4x+4

Answer 1

Answer:

-6-4=4x-2x

10=2x

x=2÷10

x=5

Answer 2

There are 2 solutions with absolute value equations.

1. |2x-6| = 4x+4

Remove absolute value:

2x-6 =4x + 4

Subtract 4x from both sides:

-2x -6 = 4

Add 6 to both sides:

-2x = 10

Divide both sides by -2:

X = -5

2nd solution

Remove absolute value and add a negative sign to the right side:

2x-6 = -4x -4

Add 4x to both sides::

6x-6 =-4

Add 6 to both sides:

6x = 2

Divide both sides by 6:

X = 2/6

X = 1/3

The two answers are x = -5 and x = 1/3
