A Tutorial on Solving Equations Part 2

This is a continuation of Solving Equations Part 1.  As I have mentioned in that post, being able to solve equations is very important since it is used for solving more complicated problems (e.g. word problems).

In this post, we are going to solve a slightly more complicated equations. We already discussed 5 examples in the first post, so we start with our sixth example.

Example 6: $8x = 4x - 12$

As I have mentioned in the previous examples, we need to isolate $x$ on one side of the equation and all the numbers on the other side. Here, we decide to put all $x$‘s on the left hand side, so we remove $4x$ on the right hand side. To do this, we subtract $4x$ from both sides of the equation. Continue Reading
