So how do you do 2 variable equations? Like:

7x + 8y = -5


How you do it?

What are the steps? Thanks!

What exactly do you want to do? Be more specific, please.

What you can do with this is draw the graph, and find the x and y intercepts.

The intercepts are at the axes, that is when one of the variables are set to zero.

For example, you get the y intercept when you set x to 0, and you get the x intercept when you set y to 0.
