This is an expression:

We don’t know the value of , so we don’t know the value of and, without more information, we can’t find the value of x. In fact, we often use expressions to represent a rule where x could have any value.

This is an equation, because it has an equal sign:

We want to know the value of that makes true

Create An Equation

Create three multi-step equations using integers less than 1000.

Make the first equation easy, the second equation medium difficulty and the third equation tricky.

On a separate piece of paper, solve each equation.

Did you get an integer solution?

Hand your questions (but not solutions) to the student behind you (back of the row hand to the front) for them to solve.
