The difference of the two numbers is 16.

difference means you subtract

so

The difference of the two numbers is 16.

the two numbers

are x and y

do you remember?

so

The difference of the two numbers is 16.

x - y

thats what the difference is

x -y is 16

do you remember what is means

is means it IS

x - y = 16

ok so

x + y = 20

but

x - y = 16


so

X + Y = 20

X - Y  = 16
