Question

Part 1: Explain, in complete sentences, how you would use the elimination method to solve the following system of equations. (4 points) Part 2: Provide the solution to the system. (2 points)

8x + 5y = 3
7x – 3y = 10

Answer 1

multiply first by 3 and second by 5

24x+15y=9
35x-15y=50
------------
59x 0 =59
x=1

24*1 +15y=9
15y=9-24
15y=-15
y=-15/15
y=-1

x=1
y=-1
