Question

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

−3

3

Answer 1

x=3, and y=3.

Given your choices, I simply substituted in.

12-3y=3
-3y=-9
y=3

and

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