I’m 78% through the pre-algebra course on Khan Academy, which I am really loving.

At 36 years old, its been probably 20 years or longer since I dabbled in anything beyond basic math.

Khan’s site though is hugely fun for me now, for whatever reason (I don’t even really remember what the impulse was to start this now anyway) — it’s like being back in school but without any stress or pressure.

And now that I’m older and ostensibly “wiser,” the utility of the whole thing seems much greater to me than it did in my youth.

As long as you perform the same operation on both sides of the equation, the equation remains balanced.

The rest is simply performing a series of arithmetic functions to break apart the complex equation in an effort to get the variable x by itself. This concept may sound daunting, but by taking away complex functions like square roots and exponents, you drastically reduce the complexity of the problem. This equation is already expressed in its simplest terms and is ready to be taken apart and solved. The basic principle behind algebra is to get the variable (x) on one side by itself and a number on the other side of the equals sign.So we get 4 times negative 18 is equal to x over 4, times 4. You divide something by 4 and multiply by 4, you're just going to be left with an x. Sometimes there are problems that need slightly more complicated equations.If this is equal to that, anything we do to that, we also have to do to this. So you subtract 2 from the right, subtract 2 from the left, and we get, on the left-hand side, negative 16 minus 2 is negative 18. And then we have positive 2 minus 2, which is just going to be 0, so we don't even have to write that.I could write just a plus 0, but I think that's a little unnecessary. And our whole goal here is to isolate the x, to solve for the x.This article has over 645,323 views, and 38 testimonials from our readers, earning it our reader-approved status.
