    solve for y in the second equation so you have y=3x-3/2 then substitute y into the first equation. solve for x. when you have x substitute it in and solve for y

    by substituting into the first equation you have 4x^2-3(3x-3/2)=0

    i tried using substitution and but i solved for x in the frist equation getting x=\[(\sqrt{3y})/2\] then i plugged it into the 2nd equation and solved for y getting y=.75 and 3 is that i all that i need to?

    you can do that, but you have to remember that when you take a square root, you have to use the positive and the negative. that's why i used the second equation to solve for y and substituted that in, because it's simpler
