Homework Help: Linear Equations

Posted by Mia on Tuesday, March 2, 2010 at 1:04pm.

Can you please help solve this equation using the substitution method? I have tried and keep getting that X and Y = 7/2, but the answer in the book states no solution, inconsistent system. What am I doing wrong? Please help! Solve the systems of equations by the substitution method.
y-x=4
x-y=3
Thank you!
