In this section, you will learn how to solve equations that contain unknown variables.You will learn how to solve equations mentally by using the multiplication table and you will also learn how to identify a solution to an equation with given numbers as well as by using inverse operations.Next, you want all the constants on the other side of the equal sign.
Like for example, this -8 and 7, I want to have them together, I want to have them on the same side of the equals sign.
So what I'm going to do is the opposite of taking away 8 is to add 8.
Since there are variables on both sides, you want to eliminate the variable from one side of the equation.
After you have done this, the variable should only be on one side of the equal sign.
Next thing I'm going t try to do is get these ms together.
I want this 5m to be with that 2m so I have to move it. The answer is going to be -5, you can kind of do that in your head.
Addition and subtraction are inverses of each other, just like division and multiplication are inverses.
There are many answers, but the coefficient of both x terms have to be the same and the constants must have different values.
So, 2x 3 = 2x 4 is an answer because it is equivalent to 3 = 4, for which there is no solution.
This educational video gives instruction on how to solve mathematical algebraic equations.
