Question

check that (-2,5/2) is a solution of 5x-4y=20.

Answer 1

no it is not
5*-2-(4*5/2)
= -10-10
= -20
therefore - 20 is not equal to 20

Answer 2

Answer:

It's Not A solution

Step-by-step explanation:

---------------------------------------------------------------------------

5(-2) - 4×(5/2) = 20 {here x = (-2) , y =(5/2) }

-10 - 20/2 = 20

-10 - 10 = 20

- 20 = 20

(-2,5/2) is Not a solution of the equation 5x - 4y = 20
