    Oh, the answer choices are: A. x - 2y = 3 4x - 5y = 9 B. 4(2y + 3) - 5y = 9 C. x + 2y = 4x - 5y D. 5x - 3y = 12 E. - 3x + 7y = -6

    And thanks for setting an example on how to engage someone who suddenly goes hostile on you. I appreciate that you didn't immediately respond with attacks :)

    ok so you have 2 equations and 2 variables, looks like we got some interesting stuff going on in the 2 equations though. notice that the first equation already gives u the value of x as 2y+3, by substitution, simply plug in the value of x which is (2y-3) into the second equation... solve for y and then plug in your value for y into x=2y+3, solve for x and we're done here :) difficult? I think not :) follow the instructions and you'll be happy :D

    x=2y+3, my bad but i hope the concept is clear though, that's most important :)

    So would my answer be B. 4(2y + 3) - 5y = 9? :)
