#### Solving for a variable in terms of other variables using multiplication or division: Advanced

An examplel of how to rearrange a formula to better suit its particular purpose. Often we need to do this because it is easier to rearrange it once instead of having to solve for a variable each…

#### Solving a two-step equation with integers

It's just what the title says. We use opposite operations on one side to eliminate values that are with the variable and perform the same operations to the other side of the equals sign to keep…
