When you are trying to solve for a variable in an equation you have to do the same operation on both sides. The basic idea/rule is that if you are trying to solve for a variable that is being multiplied by a number you will divide by such number since you are doing the "reverse" operation. With that said, we say that if the variable is being divided by a number both sides have to be multiplied by such number. In this case, the variable x is being divided by 6.5, so you have to multiply both sides by 6.5 to get the following
