Here's the Solution to this Question

(a) Suppose Q(x , y) denotes the statement “x=y+3”. Let us find the truth values of the propositions Q(1,2) and Q(3,0). Since 1\ne 5=2+3, we conclude that the proposition Q(1,2)is false. Taking into account that 3=0+3, we conclude that the proposition Q(3,0) is true.
