Answer:
Two solutions are found:
n=0 , n= 4 ....
Step-by-step explanation:
n^2-4n = 0
Take common from the given expression:
n(n-4)=0
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately;
n(n-4)=0
n = 0.
n-4 = 0.
Add 4 at both sides:
n-4+4 = 0+4
n = 4
Therefore two solutions are found:
n=0 , n= 4 ....

Step-by-step explanation:
Step-by-step explanation:
Let Number of senior citizen tickets
sold = x
Number of students tickets sold = 3.x
Number of adult tickets sold = 4 x 3x
= 12x
/* According to the problem given */
3x = x + 142
+ 3x – x = 142
2 x = 142
142 == 2
> x = 71
. Number adult tickets sold
= 12x
= 12 x 71
= 852
