What is a literal equation?

Back

A literal equation is an equation that contains two or more variables. It is often solved for one variable in terms of the others.

How do you isolate a variable in a literal equation?

Back

To isolate a variable, you perform inverse operations to move other terms to the opposite side of the equation.

What does it mean to 'solve for a variable'?

Back

To solve for a variable means to manipulate the equation to express that variable in terms of the other variables.

Front

If you have the equation 3x + 5 = 20, how do you solve for x?

Back

Subtract 5 from both sides to get 3x = 15, then divide by 3 to find x = 5.
