Answer

X=4 or X= - 10

Step one divide both sides by -4

-4(|x+3|) over -4 = -28 over -4

|x+3|=7

We know either

X+3=7 or x+3=-7

X+3=7 (possibility 1)

X+3-3= -7 - 3 (subtract three from both sides)

X=-10

Answer

X=4 or X=-10 both are the correct answer it could go either way

Step-by-step explanation:

3x² = 9 ( divide both sides by 3 )

x² = 3 ( take the square root of both sides )

x = ± \sqrt{3}
