Question 108407: solve following systems by substitution
4x-12y=5
-x+3y=-1
x=-3y+1


4(1-3y)+12y=5
4-12y+12y=5
4x=5
Double checking to see if I did these right.

You can put this solution on YOUR website!
The answer is going to be , no solution. When it is worked out, you cancel both variables.
You are close;
4x-12y=5
-x+3y=-1
=================
-x=-1-3y
x=1+3y
================
4(1+3y)-12y=5
4+12y-12y=5
4%2Bcross%2812y%29-cross%2812y%29=5
4=5
no solution
