Question

Use any method to solve the linear system:
y=1/3x+2
2x-6y=16

Answer 1

I'm guessing i should use substitution but I'm not sure :/

Answer 2

in the first equation get the y to the opposite side and the 2 to the other side. so it should be -2=1/3x-y

Answer 3

well since y is already solved shouldn't I just plug it in to the second equation???

Answer 4

oh man, lol i was going to do elimination but yeah you're right lol plug it into the 2nd equation

Answer 5

kk, when I did that and tried to solvee, x=10 over 3 or 10 thirds

Answer 6

thats weird, i went through it and distributed -6 to 1/3 x and 2
and got 2x-2x-12=16

Answer 7

so the 2x's would cancel so that wouldn't work,

Answer 8

well lets continue doing it the way i was with elimination because that seems easier... so when we put the y to the other side we will get 1/3x-y=-2
to get the y's to cancel out we would multiply that equation by -6 to get 2x+6y=-2 combine those equations and get 2x+2x+6y-6y=14
4x=14
divide 4 from both sides and get x=3.5
understand?

Answer 9

@brookester6 do you understand it?
