Answer: After washing 20 cars together, each team will have raised the same amount in total.
Step-by-step explanation:
Let x represent the number of cars that each each teams will wash for them to raise the same amount in total.
The volleyball team gets $4 per car. In addition, they have already brought in $24 from past fundraisers. This means that the total amount raised by the volleyball team after washing x cars would be
4x + 24
The wrestling team has raised $84 in the past, and they are making $1 per car today. This means that the total amount raised by the wrestling team after washing x cars would be
x + 84
For both amounts to be equal, the number of cars would be
4x + 24 = x + 84
4x - x = 84 - 24
3x = 60
x = 60/3
x = 20
Answer:

hence this line passes through
.
When 

Hence this line passes through
.
Graph is attached.
2(4z-3-21)=166-46
Combine like terms
2(4z-24)= 120
Distribute
8z-48= 120
Add 48 to both sides
8z= 168
Divide both sides by 8
z=21
Final answer: z=21
