Answer: 6 large frames and 12 small frames

Step-by-step explanation:

We define the following:

x = number of large frames

y = number of small frames

Make the following equations:

x + y = 18

19x + 9y = 222

Use system of equations to solve. We find the value of x first.

y = 18 - x

⇒ 19x + 9(18 - x) = 222

⇒ 19x + 162 - 9x = 222

⇒ 10x + 162 = 222

⇒ 10x = 60

⇒ x = 6

Find value of y:

6 + y = 18

y = 12

∴ 6 large frames and 12 small frames were purchased.

Leno4ka [110]

Answer:

$b+p=72$

$p=72-b$

Step-by-step explanation:

We can represent this situation with an equation that shows that when b and p are added, then the total number of people will be 72

The number of people who bring supplies = b

The number of people, to whom supplies are provided = p

We get ;

$b+p=72$

$p=72-b$
