Best ResponseYou've already chosen the best response.0You are looking for "The intersection of two lines". If you would like to do so algebraically: \[2x1=3x4\] Now subtract 2x from both sides \[1=x4\] Now add 4 to both sides \[3=x\] Now substitute x=3 into y = 2x1 \[y=2(3)1\] So y=5. You should see this by graphing as well. On your calculator: \[y_1=3x4\] \[y_2=2x1\] And see that they intersect at the point (3,5). Hope this helps.

Best ResponseYou've already chosen the best response.0So you understand how I got x=3? Once we have x = 3, then we can take that value of x (which is half the answer, we're looking for an x and a y) and insert it into either of the original equations. That lets us solve for y.
