Csc 201 programming assignment #5 faii'19 example: solve 5x+8y+6=4x+6y+10 and 4x+7y+5=-2x+-5y+11 solution: it to have moved the variables all to one side and the constants to the other side before transforming the equations in preparation for adding. when we're done moving things around, the system looks like this: let's multiply the first equation by -6: now we add the two equations: x+2y=4 and 6x+12y=6 -6x+-12y=-24 and 6x+12y=6 0 = -18
