Web3. Solving simultaneous equations method of elimination We illustrate the second method by solving the simultaneous linear equations: 7x+2y = 47 (1) 5x−4y = 1 (2) We are going to multiply Equation (1) by 2 because this will make the magnitude of the coeffi-cients of y the same in both equations. Equation (1) becomes 14x+4y = 94 (3)

WebJul 5, 2015 · The correct solution to your system of equations is y = − 1 7 and you want to find x. To do so, substitute this value of y into the first equation to get. − 7 x − 2 ⋅ 1 7 = 2 − 7 x = 16 7 x = − 16 49. by re-arranging and solving for x. Alternatively, you could substitute your y value into the second equation to get.
