9-35.

Solve the following systems of equations.

If you need a reminder of how to solve systems of equations, refer to the Math Notes boxes in Lessons 6.2.3 and 6.3.3.

1. $3x − 2y = 14$
$−2x + 2y ​= −10$

1. $y = 5x + 3$
$−2x − 4y ​= 10$

1. Which system above is most efficiently solved by using the Substitution Method? Explain.

2. Which system above is most efficiently solved by using the Elimination Method? Explain.
