Solving for a Variable

When it comes to finding the value of a variable, the process usually involves making sure the variable is alone on one side of an equation. This may necessitate the use of various mathematical techniques such as multiplication, division, addition, or subtraction. The ultimate aim is to identify the exact value that will validate the equation when it replaces the variable.
