Question

Check which of the following are solutions of the equation x-2y=4 (1) 0,2 (2) 2,0 (3) 4,0 (4) 1,1

Answer 1

Answer:

(4,0)

Step-by-step explanation:

x-2y = 4

substitute (0,2) we get 0-4= -4 ≠4

substitute (2,0) we get 2-0 = 2 ≠4

substitute (4,0) we get 4-0 = 4

Hence (4,0) is the correct answer
