The solution is at what point the two lines intersect. Plug y into the other equation to get: 5x-4(5-3x)=-3 Multiply it out: 5x+12x-20=-3 Combine like terms and add 20 to both sides: 17x=17 Divide both sides by 17: x=1 Now plug the x value back into any equation to get the y value. So you get y=5-3(1) --> y=2 The solution is (1, 2)
