I'd use elimination, since the coefficients are small to eliminate x, subtract the 1st two, subtract twice #1 from #3 and we have -5y - z = -18 -9y + 5z = -26 now eliminate y or z in the same way, and then plug the values back in to obtain the others.

since the slope is 1/4, you know that y will increase by 1 when x increases by 4. Since x increased from -12 to 8 (20), y will increase by 1/4 (20) = 5. So, w=6+5=11. If the slope had been -1/4, w = 6-5 = 1 #2. multiply the 1st equation by 3 and you now have 9x-6y-24=0 9x-6y-...
