In this post, I will be explaining how to solve equations. To be able to solve equations, you must first understand BEDMAS (Brackets, Exponents, Division, Multiplication, Addition, Subtraction). BEDMAS is used to remind people of the order the terms of an equation are solved in. You may also need to know how to add, subtract, multiply, and divide exponents. For this post, I will be using * (the asterisk/star symbol) to represent multiplication, this is to prevent confusion between multiplication and variables.
Let’s start off with a simple equation:
To begin we’ll use BEDMAS to figure out what term we need to solve first.
Next we need to subtract 100 from each side
Then we divide each side by 2
That leaves us with x=10, which is our answer. Now let’s try a more difficult equation that contains every component of BEDMAS.
First, we need to do the term in the brackets.
Next, we’ll solve the exponent.
Now we divide
Next, we multiply
Then we add 25 to each side
Finally, we divide each side by 180
Our answer is x=2.
A useful tip for solving equations is to always simplify when possible.
