1. Solve the system of equation using the addition method

2x-3y=11

-3x=-5y-17

2. Kate and Ernie are at a dude ranch. Kate has been horseback riding for 0.5 hours on the trail at 6 miles per hour when ernie starts riding his horse on the trail. if ernie rides at 10 miles per hour, how long will it be before he catches up to kate.

3. using a graph, determine the solution of each system of inequalities.

2x+3y<6

4x-2y> or equal too 8.
