<span>7x-6y=14 6x-y=-17 x = -4 y = -7 (SOLUTION) ; in ordered pair form (x,y) = (-4,-7)
</span><span>3x+8y=16 -9x-24y=-48 INFINITE SOLUTIONS: general form = (x,y) = ( x, -(3x/8)+2 )
Edited later: </span>7x-6y=14 6x-y=-17 From second equation 6x - y = -17, we have y = 6x +17. Substitute this in the first equation to get 7x-6y=14 >> 7x-6(6x+17)=14 >> 7x-36x-102=14 >> 7x-36x=102+14 >> -29x=116 >> x=116/(-29) >> x=-4
Now plug this value in y = 6x +17, to get y = 6(-4) + 17 = -24 +17 = -7
