Hello!
You can make two equations based on what you know
x + y = 50
5x + 3y = 190
Subtract y from both sides of the first equation
x = 50 - y
Put x into the second equation
5(50 - y) + 3y = 190
Distribute the 5
250 - 5y + 3y = 190
Combine like terms
250 - 2y = 190
Subtract 250 from both sides
-2y = -60
Divide both sides by -2
y = 30
Put y into the first equation
x + 30 = 50
Subtract 30 from both sides
x = 20

Step-by-step explanation:
Let x=3.
So, f(3-3)=f(3)-f(3), and thus f(0)=0.
