Question

PLEASE HELP! I Will Give You 20 POINTS!! Solve with absolute value. -|12-3.5x|=-5

Answer 1

2 and 4 6/7

Explanation:

• - |12 - 3.5x| = -5 ⇒ cancelling negative signs
• |12 - 3.5x| = 5
• 12 - 3.5x = ± 5 ⇒ getting rid of absolute

1. First equation

• 12 -3.5x = 5
• 3.5x = 12 -5
• 3.5x = 7
• x = 7/3.5
• x= 2

2. Second equation

• 12 - 3.5x = -5
• 3.5x = 12 +5
• 3.5x = 17
• x= 17/3.5
• x= 34/7
• x= 4 6/7
