Solve the following inequality for x.

Answer 1

A

Explanation:

Given

x - 9 ≤ 2(9 - x) ← distribute parenthesis

x - 9 ≤ 18 - 2x ( add 2x to both sides )

3x - 9 ≤ 18 ( add 9 to both sides )

3x ≤ 27 ( divide both sides by 3 )

x ≤ 9 → A

Answer 2

It's A)

Explination :

X-9 _< 2(9-x)

X-9 _< 18 - 2x

X+2x _< 18+9

3x _< 27

x _< 27/3

x _< 9
