    1. Simplify brackets 5−x−5>−2(x+4) 2. Simplify 5−x−5 to −x −x>−2(x+4) 3. Expand −x>−2x−8 4. Add 2x to both sides −x+2x>−8 5. Simplify −x+2x to x x>−8

    Marcie solved the following inequality, and her work is shown below: −2(x − 5) − 12 ≤ 4 + 6(x + 3) −2x + 10 − 12 ≤ 4 + 6x + 18 −2x − 2 ≤ 6x + 22 −8x ≤ 24 x ≤ −3 What mistake did Marcie make in solving the inequality?

    Distribute so you can eliminate the () \[Distribute so you can eliminate the () -2x+10-12\le4+6x+18\] combine like terms and simplify

    since the last line is a negative you multiply, but she divided

    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

    If you multiply or divide by a negative number when solving an inequality, you must reverse the sign. This example the last step did not flip the sign. it should have said x≥−3
