Question

3x-12>5x+2= ?

-10
-5
5
10

I just can't get the right answer

​

Answer 1

- 10

Explanation:

Solving the inequality

3x - 12 > 5x + 2 ( subtract 5x from both sides )

- 2x - 12 > 2 ( add 12 to both sides )

- 2x > 14

Divide both sides by - 2, reversing the inequality symbol as a consequence of dividing by a negative quantity

x < - 7 ← reverse inequality symbol

The value of x for x < - 7 is - 10
