Answer:

The children ticket cost is 8$

Step-by-step explanation:

I. Given a = adult and c = children

10a + 10c = 200 => 1st day

13a + 2c = 172 => 2nd day

II. Multiply 2nd day with 5

65a + 10c = 860 => simulate

III. Eliminate c value by simulate - 1st day

55a + 0 = 660

a = 660/55

a = 12 or adult ticket cost is 12$

IV. Find children ticket cost by replace a value in 2nd day

13(12) + 2c = 172

156 + 2c = 172

2c = 172 - 156

c = 8 or children ticket cost is 8$

Hope that help :)

Answer:

$\sf x = \dfrac{n - 2mp}{2m}$

Step-by-step explanation:

$\sf 3m = m + \dfrac{n}{p + x}\\$

$\sf 3m - m = \dfrac{n}{p +x}$

$\sf 2m = \dfrac{n}{p +x}$

Now cross multiply,

2m*(p +x) = n

To open the parenthesis, multiply 2m by p and x.

2mp + 2mx = n

Isolate the term with variable 'x'

2mx = n - 2mp

Now, isolate 'x', by dividing both sides by 2m

$\sf x = \dfrac{n-2mp}{2m}$
