Question

check that (0,5) is a solution of 5x-4y=20

Answer 1

No it is not

Replacing the values

X*0 - Y*5=-20

-20 is not equal to 20 so

The values do not satisfy the equation

Answer 2

Hii There!!!

Given coordinates are : ( 0,5 )
where , x = 0 and y = 5

So, in the given equation i.e, 5x - 4y = 20

Consider L.H.S
On substituting values of 'x' and 'y' we get ;

5 × 0 - 4 ( 5 )

= 0 -20

=> -20 ≠ R.H.S

Hence, ( 0,5 ) is not a solution of given equation.
