isolate the variable
If both sides of an equation are not equal, it won't be an equation any more! In solving equations, the strategy is to change both sides in the same way, so that an 'equivalent' equation is produced. An equivalent equation has the same solution as the original equation. You are aiming for an equation in which the variable is alone on one side. The quantity on the other side is the solution.
It can be either. If it takes a noun as an object, it is a preposition. It if stands alone or with other adverbs, it is an adverb. It can, rarely, be an adjective.
