Join Karin Hutchinson for an indepth discussion in this video Isolating the variable in an equation, part of Learning Algebra: Solving Equations.
 In this video, I will be talking about a term…that I will use quite often when solving equations.…And that term is isolating the variable.…Isolating means to get something by itself.…So our goal when solving equations…is going to be to get the variable by itself…on one side of the equation.…So let's take a look at a typical equation.…This equation is 2a + 4 = 8.…The variable is "a" in this equation.…The a is on the left hand side of the equation,…and I need to get that a by itself.…
So that means that I first need to…move the 4…and then I'll need to move the 2.…The process for moving the 4 and the 2…we'll get into as we begin Chapter Two.…But what I need you to know in this video…is that your ultimate goal…is to get a by itself…on one side of the equation…so that your final answer reads…a = and then the final answer.…So again, when you isolate your variable,…your goal is to get it by itself…and remove all other terms from that side.…
