Substitute the second equation into the first equation:
2y - (y + 7) = 0
2y - y - 7 = 0
y - 7 = 0
y = 7
Now, use the second equation to find the value of x:
x = 7 + 7
x = 14
Therefore, the value of x is 14.
2y - x = 0
x = y + 7
If (x,y) satisfies the given system of equations, what is the value of x?
