What do you do to get the variable by itself on one side of the equation?
Move whatever is on the side of the variable to the other side
Use the same operation as shown in the equation
Subtract the variable from both sides of the equation
Use inverse operations
All of the options listed can be used to get the variable by itself on one side of the equation. However, the most common and widely used method is to use inverse operations. By applying the inverse operation of the given operation in the equation, you can isolate the variable on one side. For example:
If the equation is x + 5 = 10, where x is the variable, you can subtract 5 from both sides to get x = 10 - 5, which simplifies to x = 5.
