Question

Solve the inequality:
3x > 72-5х
x ≤ -9
x ≥ -9
x ≥ 9
x ≤ 9

Answer 1

The correct solution is,

x > 9

(if the inequality is 3x ≥ 72-5х then the solution is x ≥ 9, so the 3rd option I suppose)

Explanation:

3x > 72-5х

adding 5x on both sides,

3x + 5x > 72

8x > 72,

dividing by 8 on both sides,

8x/8 > 72/8

x > 9
