Commutative
5. Just do 9 minus 4. 5 plus 4 equals 9
5 +9 = 9 + 5 is an example of arithmetic commutativity
13...... 9 plus 5 equals 14...... 14 minus 1 equals 13

r + 2t = -3 . . . . (A)3r - 4t = -9 . . . . (B)2*(A) + (B): 2r + 4t + 3r - 4t = -6 - 95r = - 15 so r = -3substituting in (A), t = 0So the answer is (r, t) = (-3, 0)r + 2t = -3 . . . .
