Question

Solve 3|2x + 2| − 7 = 5 for x. Show your work

Answer 1

2x + 2= +(5+7)/3
2x + 2= -(5+7)/3
solve this 2 equations for x

Answer 2

3|2x + 2| − 7 = 5 add 7 for both sides
3|2x + 2| = 12 divide both sides by 3
|2x + 2| = 4

if |a| = b then a= +or- b

thus 2x +2 = 4 or 2x+2 =-4
2x = 2 2x = -6
x=1 x=-3

Answer 3

ok thanks
