Help! I need a explanation of the Subtitution Method in laymans terms.
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. :?
