Step-by-step explanation:

Hi Anna,

Question:

What is the justification for each step in solving the inequality?

−2(x+1)≥3x+8

Select from the drop-down menus to correctly justify each step.

Solution:

−2x − 2 ≥ 3x + 8

Subtract 3x from both sides.

−2x − 2 − 3x ≥ 3x + 8 − 3x

−5x − 2 ≥ 8

Add 2 to both sides.

−5x − 2 + 2 ≥ 8 + 2

−5x ≥ 10

Divide both sides by -5

x = -2

The only step she needs to fix is option C instead of being −2x ≥ 3x + 10 it should be  −2x − 2 − 3x ≥ 3x + 8 − 3x  then −5x − 2 + 2 ≥ 8 + 2 then divide both sides by 5. She needs to add those three steps.
