How To Solve A Simple Equation - II

Education : Maths

We have seen you can solve:
2x + 6 = 12 through trial and error

The other method is to try and isolate the unknown term(s) on one side, and the known on the other. This is the best way.

Here the known numbers are 6 and 12, and the unknown is 2x.

So, we can re-arrange to get:
2x = 6, by taking 6 off each side of the equation.

Then, we can divide by 2, to get x = 3. Much better!
