HELP! Amber was asked to solve the following inequality and show all of her work. She made an error when solving.

2x − 3.5 ≥ 10.5

2x − 3.5 − 3.5 ≥ 10.5 − 3.5

2x ≥ 7

2x ≥ 7(2)

x ≥ 14

- A description of what Amber did wrong and what he should have done instead
- Your work solving the inequality


Sagot :

Amber did wrong at the second and third step : She completely simplify both sides but she has to minus 3.5 twice on the left side in order to do so. But instead, she just make them gone.
