Need to learn how to . . .

I need to learn how to do the following problems. Don't give me the answer but give me the steps leading to the answer then I will respond back with the answer.

say if you had a problem that said: tickets to a game were sold for $2 for each adult and 0.75 for each child. A total of 350 people paid $450 to see the game. How many sdult tickets were sold?



A drama team budgeted $120 for the purchase of new masks. Ugly mask cost $11 each and pretty mask cost $23 each. They purchased six mask and spent $114. How many of each type of mask did they purchase?


These are assortment problems..
1) you know the total number of items
2) you know the total price.

Examples
First..
1) Adult + Kid = 350
2) Adult*2 + Kid*.75=450
Two equations, two unknowns. Recommend solve by substution.

Second:
1) Ugliessss + Pretty=6
2) Ugly*11 + Pretty*23=114


not to sound like I am mooching the answer I still don't get it. Are you saying for the first do A+K=350,then 2A+.75K=450.
