9-11.

Solve each system of equations below. Write your solution in the form $(x, y)$. Check your solution.

1. $3x − y = 14\\ x = 2y + 8$

Use substitution to solve
for both variables.

$(4, −2)$

1. $x = 2y + 2\\ x = −y −10$

Set the two equations equal to each other.

1. $16x − y = −4\\ 2x+y=13$

Use elimination to solve
for the two variables.

$(\frac{1}{2},12)$
