Answer:
Step-by-step explanation:
Convert to a set of algebraic equations:
x+y=60,
y-x=12
Make y in terms of x:
y-x=12
y=12+x
Plugin y in terms of x to x+y=60:
x+12+x=60
Simplify to find x:
2x=60-12
2x=48
x=24
Find y based on x:
x+y=60
plugin 24 to x:
24+y=60
y=60-24
y=36
Check with the second equation:
36-24=12
The function works
x=24, y=36
