Hello!</h2>
The answer is:
The x-coordinate of the solution to the system of equations is:

<h2>
Why?</h2>
We can solve the problem writing both equations as a system of equations.
So, we are given the equations:

Then, solving by reduction we have:
Multiplying the first equation by 2 in order to reduce the variable "x", we have:


Now, substituting "y" into the first equation, to isolate "x" we have:

Hence we have that the x-coordinate of the solution to the system of equations is
