84 adults ; I did 108/9 = 12 then 12x7 = 84 because 9-2 = 7 and we wanted to find out the remaining number of people :))

What is liner equation with two variable?
- An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
- For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.
-10x² -10y² = -300 ----a
5x² + 5y² = 150 ---- b
While trying to solve this,
We can multiply the eq. b by 2 so we will get eq. c and then add to eq. a we will get 0 as the solution.
10x² + 10y² = 300 ----c
-10x² -10y² = -300 ---a
<u>Everything cutoff, we will </u><u>get 0</u><u>, and there is no solution to these equations.</u>

Answer:
20
Step-by-step explanation:
<u>25 </u> = <u> x</u>
20 16
(25*16)/20 = 20
Answer:
12:28
Step-by-step explanation:
yesterday the ratio would be 6:14 so then you double that to get 12:28
You know this is just a formula, right?
