Solve the folowing systems of equations. x + 9y=4 (1) x=3-9y (2) What is the solution of the system?

OpenStudy (mertsj):

Why don't you try replacing x in the first equation with 3-9y from the second equation?

OpenStudy (anonymous):

that eliminates all variables and you are left with 3=4. So there is no solution.
