What I Learned Today 1/12/15


I'm learning about equations and linear equations in pre-algebra.

Important: If you add, subtract, multiply or divide the expression on one side of the equation by something, then you have to do the same to the expression on the other side of the equation.

Important: When solving an equation, we can check our answer by substituting our answer back into the original equation. If the original equation is not satisfied by our answer, then we probably made a mistake and should solve the equation again.
