Multi-step equations

Multi-step equations are all equations that require you to perform more than two steps (or operations) in order to solve them. They can be simple or really hard to do, since there are no limitations on the number of steps you have to perform to get to a solution. But one thing is certain – they will require all the knowledge you gained by solving one-step equations and two-step equations. Because this is a bit more complicated, we will show you how to solve multi-step equations on two examples.

The first example is a fairly simple multi-step equation with integers that has a variable on both sides of the equation.

n + 2 = -4 + 2n

The first thing we have to do here is to get all the variables on one side and all the numbers on the other.  It does not matter on which ones you put on the right side of the equation and which ones on the left – you will still get the same result in the end. But in this case, we will save ourselves a bit of effort if we put the variables on the right side.

2 + 4 = 2n – n

Now we perform the calculations and get…

6 = n

This was easy, was it not? By making a smart choice in the beginning, we made the equation easier to solve. Otherwise, we would have to perform an additional operation. Like this:

n + 2 = -4 + 2n

n – 2n = -4 – 2

-n = -6 |*(-1)

n = 6

It does not seem like a big deal now, but thinking and a bit of planning instead of automatic solving can help you a lot when dealing with some multi-step equations.

Now, let us try to solve a more complicated equation. An equation like this one:

6n – 3(-3n + 2) = -24 + 6n

This equation requires us to perform a distribution, so we will do that first. That means we have to multiply each element between the brackets with the number in front of the brackets, or in this case “-3”.

6n – 3*(-3n) + (-3)*2 = -24 + 6n

When we clean that up a bit, we get:

6n + 9n – 6 = -24 + 6n

Now we will move the variables to the left side and the numbers to the right side.

6n + 9n – 6n = -24 + 6

When we perform the additions and subtractions, we get:

9n = -18

All that is left to do now is to divide the whole equation by 9 and…

9n = -18 |:(9)

n = 2

…we found the solution.
