Answer:
I believe it's 40/ 20 I'm sorry if it's wrong..
Subtract these 2 equations,
5x-5x +3y-y = -4-6
2y = -10
y = -5
-5 is your answer.
Do you mean an extraneous solution? I will tell you what I think. To tell if a solution is extraneous you need to go back to the original problem and check if there actually is a solution or if the solution is actually right. If not then it is extraneous.
Well 40 divided by 5 is 8 and you don't have options so I would say 8 loads a day :)
The next term in this sequence would be 18.
