Best ResponseYou've already chosen the best response.1You can use to first equation to find y in terms of x: x  y = 3 Subtracting x from both sides we get y = x  3 Multiplying both sides by 1 gives us y = x + 3 Now plug the value for y into the second of the original equations, giving: x + 3(x + 3) = 5 ...................(1) Now you just need to solve equation (1) to find the value of x.

Best ResponseYou've already chosen the best response.1x + 3(x + 3) = 5 ...................(1) Expanding the brackets gives x + 3x + 9 = 5 Adding like terms we get 4x + 9 = 5 ............(2) Now you should be able to solve equation (2).
