You forgot to include the - when dividing by 2.If Z is 450 then the third row would be 100 + (450 x 2) = 1000 instead of... 100 + (-450 x 2) = -800That would make X + Y + Z Be 80 + 100 + 450 = 630. (your answer)I have no idea where you have gotten the idea that Z is a positive number when the 3rd row's answer is a negative. 0 Reply Copy ID Copy Link

(your answer)I have no idea where you have gotten the idea that Z is a positive number when the 3rd row's answer is a negative.The third equation's answer is negative because that's what happens when you subtract a bigger number from a smaller number.It's Y - 2Z = -800, not Y + 2Z = -800. 0 Reply Copy ID Copy Link
