Let's see if you can solve these problems:  Shout out the answer if you know it! 
____ + 3 = 5 
10 - ____ = 8 
3(____) = 15 
45 / ____ = 5 
These are 1-step equations! 
A linear equation is an equation that creates a line when graphed.  The word "line" is even in the name! 
So, to solve a 1-step equation, you will need to perform one step! Yay! 
The goal when solving an equation is to have the variable on one side of the equal sign and the number (or constant) on the other side.  
The strategy for getting the variable by itself with a coefficient is to use the opposite operation.
