Question 436588
What is the value of the x variable in the solution to the following system of equations? 
2x − 3y = 3
5x − 4y = 4
--------------
If you sub 0 for x, y = -1 fits both equations, x = 0
If you sub -1 for x, the 1st eqn gives y = -5/3 and the 2nd gives y = -4/9.
--> x = 0
--------------
You can solve for x & y
2x − 3y = 3
5x − 4y = 4
8x - 12y = 12 Eqn 1 times 4
15x- 12y = 12 Eqn 2 times 4
-------------- Subtract
-7x = 0
x = 0
------
y = -1
-----------
answer choices: 
−1 
0 
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
