To find the value of x in the solution (x, y) to the system of equations, we can set the two equations equal to each other and solve for x.

9x - 1 = 2x + 3

Subtract 2x from both sides:

7x - 1 = 3

Add 1 to both sides:

7x = 4

Divide both sides by 7:

x = 4/7

So the value of x in the solution (x, y) to the system of equations is 4/7.
