Two step equations

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 solution to the equation 9 = 2s + 1?

Back

s = 4.

Front

What does it mean to perform the same operation on both sides of an equation?

Back

It means to keep the equation balanced by applying the same mathematical operation to both sides.

Front

What is the first step to solve the equation 13 = 11 - 4x?

Back

Add 4x to both sides to get 4x + 13 = 11.

Front

What is the solution to the equation 13 = 11 - 4x?

Back

x = -1/2.

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, allowing us to isolate it.

Front

What is the first step to solve the equation 2b + 6 = 16?

Back

Subtract 6 from both sides to get 2b = 10.

Front

What is the solution to the equation 2b + 6 = 16?

Back
