Best ResponseYou've already chosen the best response.0you need to find the points of intersection of the 2 lines so you are solving simultaneously I'd take the 2nd equation and rewrite it as y = 21/4  x/4 then equate the equations \[21/4 x/4 = x^2 + 6x\] and then solve for x. A really easy solution is to use graphing software and graph them, and find the points of intersection.
