2x+4y = 1 3x- 5y = 7 Multiply both equation by a number to get rid of one variable I used y because it had opposite signs so multiply top equation by 5 and bottom by 4 you get, 10x + 20y = 5 12x - 20y = 28 solve the equation we get, 22x = 33 x = 33/22 x = 1.5 substitute this value in other equation to get y 2x + 4y = 1 2(1.5) + 4y = 1 3 + 4y = 1 4y = 1-3 4y = -2 y = -2/4 y = -0.5 so answer is x = 1.5 and y = -0.5 ( 1.5, -0.5)
