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 reverse order: first eliminate the constant, then the coefficient.

Front

Solve: x/4 + 11 = 20

Back

x = 36

Front

What is the first step to solve the equation 11 = 3z + 5?

Back

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

Front

Solve: 11 = 3z + 5

Back

z = 2

Front

What does it mean to 'solve for x'?

Back

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

Front

Solve: x/3 + 5 = -1

Back

x = -18

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.
