we have the 2 equations 1- ) 5x-8y=6 2-) -6x-3y=18 multiplying the first equation by 3 and the second equation by 8 then subtracting 1-) 15x-24y=18 2-) -48x-24y=144
-48x-24y=144 (-) 15x-24y=18 ------------------------------------- -63x = 126 x=-2 substituting in equation 1 5(-2)-8y=6 -10-8y=6 -8y=16 y=-2 the soultion is (-2,-2)
