(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

Answer to Question #179461 in Discrete Mathematics for Rishail
(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
(i)
3+2=5 is true, so x=3*3+5=14
Answer: x=14
(ii)
3+1=4 is true, so (3+1=4 or 6+2-3) is true, so x=3+1=4
Answer: x=4
(iii)
2*3+3=5 if false, so (2*3+3=5 and 3*3+4=13) is false, so x=3 as at the beginning of the program
Answer: x=3
(iv)
3+1=4 is true, 3+2=5 is true, so (3+1=4 or 3+2=5) is true, so x=3+1=4
Answer: x=4
