The similarities and differences between one and two variable expressions are highlighted below.

Equation involving one variable can be written thus :

Equation involving two variables can be written thus :

.

Similarities :

The concept of representing variables in both situations are the same, with x and y depicting the variables in both scenarios.

The expression on the right - hand side is expected to be equal to the expression on the left hand side of the equation.

Differences:

Only one unknown is involved when dealing with one variable while two unknowns are associated with two variable expressions.

Equations involving one unknown are fairly straightforward to solve while those involving two variables may require the use of simultaneous equations in other to obtain a solution.
