Through the process of substitution and re-arranging, you will be able to figure out the value of y.
First, plug in your x-value to start.
[tex]3(1)-5y=-3[/tex]
Now you just have to re-arrange the formula to isolate y by itself. So if you have another number there, then just move that to the other side. Whatever you do on one side, do for the other side.
[tex]3-3-5y=-3-3[/tex]
All you need to do is to isolate/separate y by itself. The number/coefficient before a variable is usually what you need to divide because it's being multiplied by the y-value. Remember the balance rule for both sides.
From there, you will be given your y-value.
[tex] \frac{-5y}{-5} = \frac{-6}{-5} [/tex]
However, there's a trick. When a negative divides a negative, it always results in a positive.
