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

What is the first step to solve the equation 3c + 5 = 23?

Back

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

Front

What is the second step to solve the equation 3c = 18?

Back

Divide both sides by 3 to find the value of c.

Front

Solve: x/2 = -10

Back

x = -20

Front

What does it mean to isolate a variable in an equation?

Back

To isolate a variable means to get the variable alone on one side of the equation.

Front

Solve: x/12 - 5 = -6

Back

x = -12

Front

What is the first step to solve the equation 4 + k/2 = -3?

Back

Subtract 4 from both sides.

Front

What is the solution to the equation 4 + k/2 = -3?

Back

k = -14

Front

Solve: x/4 - 3 = 9

Back

x = 48

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations help to undo the operations applied to the variable, allowing us to isolate it.
