memorize the conversion units. 1000J=1kJ 1 cal= 4.1868 J 1k=1000 units so as an example, then on the second 2970kcal(4.1868J/cal) Then immediately check the units, to make certain the units cancel out to leave what you want. In this case... kcal*J/(cal) leaves kJ do the math.

Multiply first equation by 2. Assuming that y was accidentally eliminated in the second equation. 4x - 10y = 6 -4x + 10y = -6 Adding the two together: 0 = 0. One equation is just the negative of the other. In other words, if you multiply one equation by -1, you get the other.
