Question

Solve 3 - x/2 > 15..

Answer 1

A. x ≤ 24

Explanation:

• 
  `\small \sf \: 3 - (x)/(2) ≥ 15 \\`

multiply both side by 2 . Since 2 is the positive the inequality direction remains the same.

• 6 - x ≥ 30

subtract 6 from both sides

• 6 - 6 - x ≥ 30 - 6
• -x ≥ 24

Divide both side by - 1. Since -1 is negative, the inequality direction remains the change.

• x ≤ -24

Answer 2

x ≥-24

Explanation:

3 - x/2 ≥ 15

Subtract 3 from each side

3-3 - x/2 ≥ 15-3

-x/2 ≥12

Multiply by -2

-x/2 * -2 ≥12 *-2

x ≥-24
