Use substitution to solve the system of equations given below.
8x  4y = 16
2x  y = 4

2x  y = 4
Subtract 4 and add y to both sides of the above equation.
y = 2x 4
8x  4y = 16
Substitute 2x4 for y in last equation and solve for x. Insert that value into the first equation and solve for y. Check by inserting both values into the second equation.
