2x  2x = 0 2y  y = 3y 5z + 3z = 8z Hence 2x  2y + 5z  2x  y + 3z = (2x  2x) + (2y  y) + (5z + 3z) = ...what?

C'mon. This is now a reading exercise. 2x  2x = 0 2y  y = 3y 5z + 3z = 8z Hence 2x  2y + 5z  2x  y + 3z = (2x  2x) + (2y  y) + (5z + 3z) = 0 + what + what

Given that: 2x  2x = 0 2y  y = 3y 5z + 3z = 8z it follows that ... 2x  2y + 5z  2x  y + 3z = (2x  2x) + (2y  y) + (5z + 3z) = 0 + 3y + 8z Hence the final answer is 3y + 8z.

I recommend you take a blank piece of paper. Write down the original expression and see if you obtain the answer again without looking at this web site. This is how I learnt this stuff. Repetition.
