WebThe variable is the letter on the left-hand side (LHS) of the equation. The variable is multiplied by two. I want the x to stand alone on one side of the equation. Since the x is multiplied by 2, I need to divide on both sides by 2, in order to get the variable by itself.This is called "dividing through by 2", and it looks like this: Web2 (-3) + 1 = (-3) - 2 -5 = -5 The symmetric property of equality is also helpful in the solution of equations. This property states If a = b then b = a This enables us to interchange the members of an equation whenever we please without having to be concerned with any changes of sign. Thus, If 4 = x + 2 then x + 2 = 4
