Example of a problem: y=-x-1

4x-3y=24

Solution:

Step 1. Solve either of the equations for one variable in terms of the other. Apparently that one was done.

Step 2. Substitute the expression from step 1 into the other equation.

Subtitute the expression -x-1 for y in the other equation.

y=-x-1 4x-3y= 24 :?:

4x-3(-x-1) =24

I need some help with this laguage. Don't speak or understand algebra well. :?
