(b) What is the value of x after each of these statements is encountered in a computer program, if x =3 before the statement is reached?
(i) if x +2=5 then x = 3*x +5
(ii) if (x +1=4) OR (2x +2=3) then x = x +1
(iii) if (2x +3=5) AND (3x +4=13) then x = x^2 +x+7
(iv) if (x +1=4) OR (x +2=5) then x = x +1
