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.

Solve for s: -2 = 4r + s

Back

s = -2 - 4r

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.

What is the purpose of rearranging equations?

Back

Rearranging equations allows us to express one variable in terms of others, making it easier to solve for specific variables.
