Question

Change the inequalities below to get 'y' by itself.(Please help me. I don't get how to do inequalities.)

x - y > 4

Answer 1

the answer would be y<4

Answer 2

y < x - 4

Explanation:

First, move the x over to the other side by subtracting x from both sides. This will get you -y > -x + 4.

Divide both sides by -1 to get rid of the -1 in front of y. Since this is an inequality, dividing or multiplying by a negative number means that you have to flip the sign. We are dividing by a negative number, so flip > to <. The signs on both sides change to get y < x - 4.
