2|x + 2|= 4 ( solve the linear equation or inequality for x)

Answer 1

2|x+2|=4

To solve, you have to isolate the absolute value to one side of the equation by dividing both sides by 2 and simplifying.

2|x+2|/2=4/2

|x+2|=2

Now this splits into 2 equations.

x+2=2 and x+2=-2

x+2-2=2-2 and x+2-2=-2-4

Simplify to

x=0 and x=-4
