Question

Solve the inequality y-2<7

Answer 1

Treat inequalities as if they are linear equations. First add 2 to both sides to isolate the y variable. That would leave you with y<9.
y<9

BTW sorry if I explained it bad, I'm not good at explaining things

Answer 2

y < 9

Explanation:

y - 2 < 7

This is a one-step inequality. You have y - 2 on the left side. You want y alone on the left side. If you add 2 to the left side, you eliminate the -2. You must do the same operation to both sides of an inequality, so add 2 to both sides of the inequality to eliminate the -2 on the left side.

y - 2 + 2 < 7 + 2

y < 9

Answer: y < 9
