Respuesta :

In this case, we'll have to carry out several steps to find the solution.

Step 01:

data:

city museum

Step 02:

system of equations:

x = # child tickets

y = # adult tickets

equations:

x + y = 170 eq. 1

5.90x + 9.40y = 1332 eq.2

x + y = 170 * (- 5.90)

5.90x + 9.40y = 1332

-5.90x - 5.90y = - 1003

5.90x + 9.40y = 1332

--------------------------------

3.5y = 329

y = 329 / 3.5

y = 94

The answer is:

# adult tickets = 94
