Front

What is a two-step equation?

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 the inverse operations in the reverse order of how they are applied.

Front

What is the first step to solve the equation 9 = 2s + 1?

Back

Subtract 1 from both sides to get 8 = 2s.

Front

What is the second step to solve the equation 8 = 2s?

Back

Divide both sides by 2 to find s = 4.

Front

How do you solve the equation 3n + 4 = 7?

Back

Subtract 4 from both sides to get 3n = 3, then divide by 3 to find n = 1.

Front

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

Back

Subtract 5 from both sides to get 3c = 18, then divide by 3 to find c = 6.

Front

What is the first step to solve the equation 7k - 14 = 42?

Back

Add 14 to both sides to get 7k = 56.

Front

What is the second step to solve the equation 7k = 56?

Back

Divide both sides by 7 to find k = 8.

Front

What does it mean to solve for a variable?

Back

To solve for a variable means to find the value of that variable that makes the equation true.

Front
