##### There are processes or steps you can use to solve problems, like in math. Where do we see these processes in real-life situations?

How can we solve for x?Click here to watch the video.

x + 7 = 11

An opposite mathematical operation and will undo the operation.

Inverse operations

x + 4 = 21

x - 4 = 11

The animal shelter decided to place 2 over 3 of the 15 blankets they received as donations in the cat crates. How many blankets will be used in cat crates?

The shelter also received a package of large dog treats. The box says small dogs should be given 1 fourth of a treat. If there are 30 large treats in the box, how many small dogs can be given a treat?

The animal shelter noticed they had two open bags of the same type of dog food. One bag was 1 third full and the other was 2 over 5 full. How much food do they have in all?

Here are some examples.

##### How does this work in the Real World?
