Let P(x,y)P (x, y) denotes the equation "x+y=8x+y=8". Let us find the truth values of the Propositions P(2,2),P(0,4).P (2,2), P (0,4).

Since 2+2=48,2+2=4\ne 8, we conclude that the truth value of the Proposition P(2,2)P (2,2) is false.

Taking into account that 0+4=48,0+4=4\ne 8, we conclude that the truth value of the Propositions P(0,4)P (0,4) is false.
