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

4x _ 3y = 3
5x _ 4y = 3

The two equations given in the question are

4x _ 3y = 3
And
5x _ 4y = 3
Multiplying the first equation by 4 and the second equation by 3, we get
16x - 12y = 12
15x - 12y = 9
Subtracting the second equation from the first equation, we get
x = 3

I hope the above procedure is clear enough for you to understand. I hope that this is the answer that you were looking for and the answer has actually come to your great help.
