What is the value ofxafter each of these statements is encountered in a computer program, if $x=1$before the statement is reached?

a) if $x+2=3$then $x:=x+1$

b) if $\left(x+1=3\right)$OR $\left(2x+2=3\right)$then $x:x+1$

c) if $\left(2x+3=5\right)$AND $\left(3x+4=7\right)$then

   $x:=x+1$

d) if $\left(x+1=2\right)$XOR $\left(x+2=3\right)$then $x:=x+1$

e) if $x<2$then $x:=x+1$
