Question

How do you solve the system 6x−2y=2 and 9x−3y=1?

Answer 1

6x-2y=2______(1)

9x-3y=1_______(2)

3 (6x-2y=2)

2 (9x-3y=1)

18x-6y=6_______(1)

18x-6y=2

- + -

___________

-12y=4

-y=4/12

y=-1/3

y=-1/3 put in equation ( 1 )

6x-2y=2______(1)

6x-2(-1/3)=2

6x+2/3=2

18x+2=6

18x=6-2

18x=4

x=4/18

x=2/9
