Question

Solve the system of equations below using the linear combination method (elimination). Then, check your work.

x-2y=2
x-y=6

Answer 1

Answer: Solution- (10,4)

Explanation:

x-2y=2 x-y=6 x-2(4)=2

-1(x-y=6) x-8=2

-x+y=-6 +8 +8

x=10

x-2y=2

-x+y=-6 10-2(4)=2

-y=-4 10-8=2

-1 -1 2=2

y=4
