Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step by performing the same operation on both sides of the equation.

Front

Back

Multiply both sides by -8 to get c = -96.

Subtract 8 from both sides to find n = 17.

Front

What is the principle of balancing equations in algebra?

Back

The principle states that whatever you do to one side of the equation, you must do to the other side to maintain equality.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side by itself.

Front

Back

Add 5 to both sides to find x = 15.

Front

Back

Divide both sides by 3 to get y = 4.
