Question

Solve the inequality.
5x - 7 < 8x + 8
The solution set is x |

Answer 1

-5 < x is correct, I double check her answer

Answer 2

- 5 < x

Explanation:

To solve, we need to isolate the variable: x

5x - 7 < 8x + 8

Subtract 5x from both sides

5x - 5x -7 < 8x -5x + 8

- 7 < 3x + 8

Subtract 8 from both sides

- 7 -8 < 3x + 8 -8

-15< 3x

Divide both sides by 3

- 15/3< 3x/3

- 5 < x
