2x+5y=20 select the ordered pair that is a solution to the equation

The ordered pair that is a solution to the equation  (5, 2)

Step-by-step explanation:

It is given that,

2x + 5y = 20

To find the ordered pairs

Multiples of 2 are,

2, 4, 6, 8, 10, 12

Multiples of 5 are,

5, 10, 15, 20,...

20 can be written as,

20 = 2x + 5y

2x is the multiple of 2 and 5y is the multiple of 5

From the above data we get, 20 = 10 + 10

2x = 10 then x = 5

5y = 10 then y = 2

Therefore  the ordered pair that is a solution to the equation  (5, 2)

thats not a system of equations, that is a solution

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
