Equations

This section deals with solving equations. Basically we solve equations by undoing the order of operations, writing simpler and simpler equivalent equations until we arrive at the solution(s).

For example, to solve one-step equations like

Similarly, we have two-step equations:

Now we can do multiple-step equations. Sometimes, the variable is on both sides of the equation:

That was so exciting, let’s do another!
