To solve this system of equations using substitution, we can start by solving the second equation for x:
x = 22 + 6y
Now, we can substitute this expression for x into the first equation:
5(22 + 6y) + 2y = 14
110 + 30y + 2y = 14
32y = -96
y = -3
Now that we have found the value of y, we can substitute it back into the second equation to solve for x:
x = 22 + 6(-3)
x = 22 - 18
x = 4
Therefore, the solution to the system of equations is:
x = 4
y = -3
