Question

How do I solve this?

Answer 1

You want to get y by itself.
To do this with the equation 13 -3y < -5 you want to subtract 13 from both sides.

13 -3y < -5
-13 -13

This will get the -3y by itself.

-3y < -18

After this, divide by -3 on both sides to solve for y.

-3y < -18
—— ——
-3 -3

When you divide by a negative in an inequality, remember to flip the inequality sign.

y > 6

There you go!

Answer 2

The < is just like and equal sign just looks a little different think of it that was for the first couple steps. So you have 13-3y<-5. First do, -5+13=8. Now you have -3y<8. Then your want to do 8 divided by -3 and you get=-2.666666667 and that equals y.

-2.7=y then make that equal sign into the normal sign again. -2.7
