What is a two-step equation?

Back

A two-step equation is an equation that requires two operations to solve for the variable.

Front

What is the first step in solving the equation 2x + 3 = 11?

Back

The first step is to subtract 3 from both sides to get 2x = 8.

Front

What is the second step in solving the equation 2x = 8?

Back

The second step is to divide both sides by 2 to find x = 4.

Front

How can you check if your solution to an equation is correct?

Back

You can check your solution by substituting the value back into the original equation to see if both sides are equal.

Front

What is a variable in an equation?

Back

A variable is a symbol, often a letter, that represents an unknown value in an equation.
