Question

is (4,0) is a solution of x-2y=4?
​

Answer 1

Answer:

x-2y =4

x=4,y=0

4-2(0)=4

Answer 2

Answer:

Yes

Step-by-step explanation:

It is known that if the (x, y) values satisfy the equation, then it is a  solution of the equation.

Assuming $(x, y) = (4, 0)$,

$x = 4\\y = 0$

Putting the values of x and y in the equation, we get,

$4 - 2 * 0 = 4$

$4 - 0 = 4$

$4 = 4$

The equation is satisfied.

Hence, $(4, 0)$ is a solution of the equation $x - 2y = 4$.
