2
Notice the 4x and -4x
They can be "eliminated" when combining the equations together. We do this to solve systems of equations when both are in Standard Form and they have inverse coefficients. (matching but opposite signs)
3
Notice the -4y and -4y
Here the coefficients match exactly which means they cannot be eliminated yet. We need to multiply one of the equations by -1 first before "eliminating" the y-variables.
