A small order comes with 3 cheese sticks and a large 6 If 7 orders total 42 how many times were the size ordered?

Large orders: y

Equations:

$$3x+6y=42$$

$$x+y=7$$

Solving the second equation for x:

$$x=7-y$$

Substituting into the first equation:

$$3(7-y)+6y=42$$

$$21-3y+6y=42$$

$$3y=21$$

$$y=7$$

Substituting y back into the equation for x:

$$x=7-7$$

$$x=0$$

Therefore, there were 0 small orders and 7 large orders.
