so the substitution method states that you need to subsitute one variable for another. Lets substitue for y, how do we do this? Solve for y with ethier equation.

i've been sitting here for like half an hour looking through the steps on how to do it

take one of those equations and solve for y, you have done this before.

I did, but i ended up with 4y= 3x+2....and that's not right

it would be 2y=3x+2 where did u get the 4?

3x2y=2 you subtract 3x 2y=3x+2 then what?

teague19 Group TitleBest ResponseYou've already chosen the best response.0
that is the original equation you divide both sides by 2 to get y by itself just like we did on that other paper

0.o no were at 2y=3x+2 if you divide 2 you get y=3/2x+1

that's what i had at first, but then you said the original equation was something different

I did not and you never had that you had 3x+y=1 you still need to solve for y

teague19 Group TitleBest ResponseYou've already chosen the best response.0
now that you have solved for y uou can plug that equation in for the y in your second equation

x+2y=6 3x2y=2 im gonna use the top one becuase its easier but x+2y=6 x x 2y=x+6 /2 /2 y=(1/2)x+3 now take the other equation solve for y and SUBSTITUTE the Y;s y=(1/2)x+3 then solve for 3x2y=2 2y=3x+2 /2 /2 y=(3/2)x+1 y=y (3/2)x+1 = (1/2)x+3 (4/2)x=2 *2 *2 4x=4 x=1
