Steps For Solving Equations

For a example, say you have the problem x+8=10. you have to figure out what x equals. The x is called a variable. The variable can be any other letter. The first step to do that is split both sides of the equals sign so you have x+8 on one side, and 10 on the other. You always use in this case the number 8 and since you are doing addition, you would subtract 8 from the numbers 8 and 10. 8 and 8 are not anything anymore, and 10 is now 2 and then you figure out that x=2.
Then, to make sure you are right, you have to check it. First you rewrite the problem. x+8=10. Next, you plug in the answer you got. 2+8=10. You see two tens so then you write down 10=10 because these are both your answers. Lastly, you write down what the variable equals. x=2.
