Next, "move" the other numbers to the right side of the equation:
Simplify:
Now, divide both sides by:
Thus, you get:
Example Question #90 :Equations
Which number can fill in the blank to complete the equation correctly?
___
Fill in the blank with a number that will make the equation true. On the right side,, so the left side needs to equalalso. "Something". If you test the answers,is the number that makes the equation true, sois the correct answer.
Alternatively,is the same as, so "something". That "something" would be, sois the correct answer.
