Front

What is the first step in solving the equation 3c + 5 = 23?

Back

Subtract 5 from both sides to isolate the term with the variable.

Front

What is the second step in solving the equation 3c + 5 = 23?

Back

Divide both sides by 3 to solve for c.

Front

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

Back

To isolate a variable means to manipulate the equation so that the variable is on one side and all other terms are on the other side.

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable, helping to isolate it.
