Net income = total revenue - cost
For example, if a company sold 100 loaves of bread for $100 dollars. The cost of making the bread is $50. The revenue is $100 and the net income is $50 (100 - 50).

Multiplying both sides of a rational equation by a variable expression introduces the possibility of extraneous solutions. Therefore, we must check the solutions against the set of restrictions. If a solution is a restriction, then it is not part of the domain and is extraneous.
Answer:
yz + z = -22
Step-by-step explanation:
Ok so you are already the number that y = 10 and z = -2. You will plug these number in the equation in order to find the answer. :-
y = 10 and z = -2
yz + z
<u>10(-2)</u> - 2
<u>-20 - 2</u>
-22
Hope this helps, thank you :) !!
