印刷 X Y 7 3x Y 1 Graphical Method X Y 7 3x Y 1 Graphical Method Josspixcto6 Explanation Subtracting equations, x − 2x = 2 − − 1 −x = 3 x = − 3 y = 2 −x = 2 − −3 = 5 Check −3 5 = 2 √Step1 The first step is to multiply or divide both the linear equations with a nonzero number to get a common coefficient of any one of the variables in both equations Step2 Add or subtract both the equations such that the same terms will get eliminated 2x+x-y/6=2 x-2x+y/3=1 by elimination method
