Finding Variables Using Division

Today in math we learned how to find variables using division. Example:

2x=8

2/2x=8/2

X=4

By dividing the 2 by 2 in cancels itself out and then when you divide 8 by 2 you get the answer. You can check if your answer is right just by doing the question with the answer in place of the variable. Example: 2(4)=8
