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

Note: The expression $x$:$=y$ means "set the new value of $x$ equal to the current value of $y.$

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

$($b$)$ if $)=(3$ OR $)=(3$ then $x$:$=x+1$

$($c$)$ if $)=(5$ AND $)=(7$ then $x$:$=x-1$

$($d$)$ if $)=(2$ XOR $x+2=3$ then $x$:$=x-1$

$($e$)$ if $x<mn\; id="EditorElement\_6533224">2</mn>$ then $x$:$=3$
