let the two numbers be x and y
From the first sentence,
xy=24
x+y=10
Then make y in equation 2 the subject of the formular and substitute in equation 1
x+y=10
y=10-x
substituting in equation 2
x(10-x)=24
open the bracket
10x-x^2=24
=-x^2+10x=24
Transfer the constant to the left hand side
=-x^2+10x-24=0
Then factorise completely

It's very simple just divide 21.75 by five and that's your answer did you want me to do it?
X. Y
12 —> 4
8 —> 8/3
13 —> 13/3
Substitute x values for y.
y = 1/3(12)
y=4
