Question

How do I solve this system of linear equation using the substitution method?

4x-12y=15
x-3y=4

Answer 1

pick one of the equations to simplify for these its easiest to make x-3y=4 and say x=4+3y and sub that into the x of the other equation

Answer 2

if your equations are written correctly, what rubymonkey16 said should work, but when I tried it, it was failing.

Answer 3

Yes, that's exactly what I did and I was failing, too.

Answer 4

could the answer just be that there is no solution

Answer 5

Yes, that's probably why I've been struggling. Thanks. :)
