Answer: 210 tickets
Explanation:
1. Multiply the number of tickets he sold on Monday (21) by 3. (21x3=63)
2. Multiply the number of tickets he sold on Tuesday (63) by 2. (63x2=126)
3. Add all of those together to get the answer. (21+63+126=210)

Answer:
x=9
Step-by-step explanation:
You have two equations.
since the second is already isolated, sub in x-4 for every y in equation 1 so that
![x^{2} - 4 [(x-4)^{2}] =16 ](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20-%204%20%5B%28x-4%29%5E%7B2%7D%5D%20%3D16%0A%20)
expand, collect like terms, factor to find x, then plug x value back into original equation to find y
