After pyruvate is formed, it must either be converted to another molecule to enter the citric acid cycle and ultimately produce ATP by utilizing the electron-transport chain, or go through alternate pathways to produce NAD . Identify the products formed in the pathway of pyruvate and indicate whether NADH H or NAD are produced under aerobic and anaerobic respiration.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
