Question

5y - 3 < 13

Answer 1

Treat the < as an equal sign for a minute to solve the equation. The first thing you want to do is get "y" by itself.

5y-3 < 13

Let's just imagine the left side of the equation first. Let's say you have 5 bags of oranges, each containing a certain number of oranges. You open a bag and take away 3 oranges (notice the minus 3). What's the easiest way to get back that 5 bags of oranges? Well....add 3 oranges again. So let's do that to the left and right side.

5y - 3 + 3 < 13+3
Or...
5y < 16

Now we have to ask ourselves how we can have only one bag of oranges. Well...divide the 5 bags by 5. So do that now:

5y/5 = y
16/5 = 3 1/5

So y has to be less than 3 1/5 oranges per bag.

y < 3 1/5

Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.

Add 3 to both sides and then divide both sides by 5 to simplify.
