Question 106834: solve each systems by substitution:
4x-12y=5
-x+ 3y=-1

4x-12y=5
-x%2B+3y=-1
Solving -x%2B3y=-1,
-x%2B3y=-1
-x%2B3y-3y=-1-3y
-x%2B3y-3y=-3y-1
-x%2B0==-3y-1
-x=-3y-1
x=3y%2B1
Substituting x=3y%2B1 to 4x-12y=5,
4%283y%2B1%29-12y=5
%2812y%2B4%29-12y=5
12y%2B4-12y=5
%2812y-12y%29%2B4=5
0%2B4=5
4=5 WHAT?


The equations led into a contradictory and false statement

Therefore, there is no solution.
