Answer:
Here's what i know:
x + y = 23
3y / 20 =x
Here we can use substitution to help find our answer:
y + 3y/20 = 23
20y/20 + 3y/20 = 23
23y/20 = 23
23y = 23 * 20
y = 23 * 20 / 23
y = 20
x + 20 = 23
x = 3

Step-by-step explanation:
Answer:

Step-by-step explanation:
The given function is

We need to find all real zeros of the given function.
Equate y=0, to find all real zeros of the given function.

Subtract 1 from both sides.


Divide both sides by 3.


Therefore, the real zero of the function is -1/3.
