1) 3x-2y=2 2) 2x+8y=6 3) 3+2x-y=0

5x-5y=10 -5x-5y=10 -3-7y=10x

Thank you for the opportunity to help you with your question!

1) multiply first equation by 5 and second by -3

15x-10y=10

-15x+15y=-30

5y=-20

y=-4

put Y in first equation

3x-2(-4)=2

x=-2

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

2)Multiply first equation by 5 and second by 2

10x+40y=30

-10x-10y=20

30y=50

y=5/3

put y in equation first

2x+8(5/3)=6

2x=6-40/3

x=11/3

(x,y)=(11/3,5/3)

3)multiply first equation by -7

-14x+7y=21

-10x-7y=3

x=-1

put x in second equation

-7y=-7

y=1

(x,y)=(-1,1)
