x=2/5, x=-6
Step-by-step explanation:
|4 - 2x| = |3x + 2| =
4-2x=3x+2
-2x-3x=2-4
-5x=-2
x=-2/-5=2/5 possibility 1
-2x+4 = - (3x+2) possibility 2
-2x+4=-3x-2 (Simplify both sides of the equation)
-2x+4+3x=-3x-2+3x
x+4=-2
x+4-4=-2-4 (Subtract 4 from both sides)
x=-6
Check answers:
2/5 (Works in original equation)
x=-6 (Works in original equation)
