Question

check which of the following are solution of the equation x-2y=4 and which are not
(0,2)
(2,0)
(4,0)​

Answer 1

Answer:

(4,0) is the solution and others are not

Step-by-step explanation:

Just Put the value of x and y in the equation and check.

if (0,2),

0-2(2) = 4

-4 ≠ 4

Therefore it is not the solution

if (2,0),

2-2(0) = 4

2 ≠ 4

Therefore it is not the solution

If (4,0)

4-2(0) = 4

4 = 4

Therefore it is the solution
