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