Best ResponseYou've already chosen the best response.0no u could use it. This is wht i did: 2x+y=13 xy=15 2x+y=13 y=132x then substitute y into the othr equation. x(132x)=15 13x2x^2=15 2x^2+13x15=0 you could use the quadratic formula.I chose to factor it.You will get the same answer. (2x+3)(x5) x=5 or 3/2 5y=15 y=3 or 3/2y=15 y=10 fina answr can be 10 , 3/2, 3/2 or 5, 5, 3
