Just treat them as x and y. No trick to the mixed numbers because it will happen automatically depending on the numbers use.
x + y = 16
x - y = 5
add the two equations
2x = 21
Can you finish from here?

2x= 10.5
using either equation to find Y
x + Y= 21
10.5 + Y=16
16-10.5
y= 5.50
check: x+y=21 10.5+5.50=16
x-y=5 10.5-5.50=5
