What is the value of the x variable in the solution to the following system of equations?

4x − 3y = 3
5x − 4y = 3

x can be any number as there are infinitely many solutions to this system

There is no x value as there is no solution to this system

anonymous · Answer

4x-3y=3 /*4
16x-12y=12    A
5x-4y=3  /*3
15x-12y=9     B

Subtract B from A to get 
x=3
