Back

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

Front

How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform inverse operations in the reverse order of how they are applied.

Front

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

Back

Subtract 5 from both sides of the equation.

Front

What is the solution to the equation 3k + 5 = 23?

Back

k = 6.

Front

What operation do you perform to both sides of the equation 5b - 6 = 24 after adding 6?

Back

Divide both sides by 5.

Front

What is the solution to the equation x + 7 = 12?

Back

x = 5.

Front

What is the purpose of performing the same operation on both sides of an equation?

Back

To maintain the equality of the equation.

Front

How do you solve the equation -4x + 1 = 21?

Back

Subtract 1 from both sides, then divide by -4.

Front

What is the solution to the equation -4x + 1 = 21?

Back

x = -5.

Front

What does it mean to 'combine like terms' in an equation?

Back

Combining like terms means to simplify expressions by adding or subtracting terms that have the same variable raised to the same power.
