Question

Use the elimination method to solve the system of equations.
2x+3y=8
Xx - y = 9

Answer 1

Answer:

Answer is x = -11, and y = 10

Step-by-step explanation:

2x+3y=8

x-y=9

So what you do is multiply your x by 2 so now you have.

2x+3y=8

2x-2y=18    subtract

0x-y=-10

-y=-10

y=10, now you know so substitute it to find X.

2x+3(10) = 8

2x+30=8

2x= -22

x=-11

So know we know the Answer is x = -11, and y = 10
