What mistake did Marcie make in solving the inequality?
She subtracted 6x from both sides when she should have added 2x.
She added 2 to both sides when she should have subtracted 22.
When dividing by −8, she did not change the ≤ to ≥.
She did not make a mistake.
So basically, all we have to do is change the signs when we multiply or divide by a negative so our answer is "When dividing by -8, she did not change the signs.
