Step 1
(i) On substituting y = 0 in the above equation, we get 3 x = 12 so that x = 4. Thus, the ordered pair (4,0) satisfies the above equation.
Step 2
(ii) On substituting y = 3 in the above equation, we get 3 x + 15 = 12   or , 3 x = 12 15 = 3 so that x = 1. Thus, the ordered pair (-1,3) satisfies the above equation.
Step 2
(iii) On substituting y = 3 in the above equation, we get 3 x 15 = 12   or , 3 x = 12 + 15 = 27   so that   x = 9. Thus, the ordered pair (9,-3) satisfies the above equation.
