Homework Help: Algebra

Posted by Jim on Friday, November 9, 2012 at 1:35pm.

I need help solving this set of equations by substitution.

3x − y + 5 = 0

I originally used (3x+5=y) and came up with (x=.333 and x=-2) but when I substitute it into the original equation I get (y=2 and y=1) and it is wrong according to my homework. Please help me!
