What would be the correct setup for solving for X?

|X+3| = 5

• X+3= 5 and X+3= -5

• X+3= 5 ad X-3= 5

• X+3= -5 and X-3 = -5

• X+3= 5 and -X-3= -5

Solve for X

|X|=7

• X= 7

• X= -7

• X= 7 and X= -7

• No Solution

What would be the correct way to write the problem before solving?

2|x-1|-6=4

• |x-1|=5

• x-1=5

• |x-1|=-5

• x-1=-5

Solve for x
l 4x−3 l = 17

• x = 5 and x =-3.5
• x = 0 and x = -5
• x = 10 and x = -10
• No Solution

Solve:  |x + 3| < 8

• x > 5 or x < -11
• -11 < x < 5

• x > 11 or x < -5

• 5 < x < 11

Solve:
 |x + 3| > 8

• x > 5 or x < -11
• -11 < x < 5

• x > 11 or x < -5

• -5 < x < 11
