Best ResponseYou've already chosen the best response.0Okay, say you have two linear equations that need solving.\[a*x + b*y = c\] and \[d*x+e*y=f.\] Now, you solve one equation for x:\[x = (cb*y)/d.\] Plug that value for x into your second equation, and solve for a value of y.

Best ResponseYou've already chosen the best response.0After you have that value of y, you plug it back into either equation, and you'll get the value of x. :)

Best ResponseYou've already chosen the best response.0You mean, 3x+12y = 15?

Best ResponseYou've already chosen the best response.0If they coincide, or are the exact same line, then one equation will be the same as the other equation  just multiplying every term by the same factor.

Best ResponseYou've already chosen the best response.0do you know how to solve each equation for "y"?

Best ResponseYou've already chosen the best response.0x  2y = 1; how would you solve for "y"?

Best ResponseYou've already chosen the best response.0we have to go back to the basics of equations with this; we want to get that "y" all by itself on one side of the equation and everything else to the other side; does that sound familiar?

Best ResponseYou've already chosen the best response.0the basic rule of thumb is: whatever you do to one side, HAS to be done to the other inorder for it to stay equal.
