The key to this problem is knowing the difference between expression and equation. An expression could have one or more variables. An equation is made up of two (2) expessions joined together with an equal sign. If a variable/s are used in a "equation" it might yield "some" solutions, one solution or no solutions. An expression gives a new solution for "each" value of y.
