     n + 5 = 14

Variable - a letter that represents a number in an algebraic expression or equation.
     n + 5 = 14

Constant - the integer in an algebraic expression or equation.

     3x = 27


Steps to solve:
 - Isolate the variable.
 - Cancel the constant using zero pair.
 - Balance - do it to the other side.

    Jae Anne, great explanations! Your writing in your pictures were a little too tiny, so next time add a link and make your printing larger.

    Jae Anne, good job! Clear explanations, but your printing in your pictures were a little too tiny. Next time add a link and make your printing more larger.
