Epic Equations

By Brendan Rucci

Solving 1 Step EquationsIf you want to take yourself and some friends to the movies and it costs $10 per ticket and you have $50 how many people can you take. To solve this equation you must use the rules for solving equations.

• First, divide the problem by the equals sign.• Next, do the inverse operation to get the

variable alone.ex. 10n=50

10 10 n=5

Now You Try

1. 7+n=22

2. X-12=37

3. 14a=42

4. b=104

Solving 2 step Equations

Say if you buy 3 tickets to the movies and spend $4 on popcorn and your final cost is $31. How could you possibly figure out how much each ticket cost? BUY USING THE RULES FOR 2 STEP EQUATIONS!

1. First divide by the equals sign.2. Then, circle the variable.3. Next, get rid of the number next to the variable

with inverse operations.4. Finally, multiply or divide.

Your Turn

1. 5+6n=-1

2. 9-8q=47

3. 16=2r+6

4. -16=-2r+6

5. 11(a+3)=90

If a movie theater makes $882 in 5 hours, including the $52 made at the snack stand, how much money was made per hour?

If the movie Harry Potter and the Deathly Hallows makes $3,250 million in 5 days, but the movie costs $1,250 million to make that movie; how much did the movie profit per day?

If a theater makes $450 in an hour, and it costs $950 to pay the employees; at this rate how much money will they make.
