Solving 2 step equations

Front

What is a two-step equation?

Back

An equation that requires two operations to solve for the variable.

Front

What is the FIRST step in solving a two-step equation?

Back

Add or subtract the constant term from both sides.

Front

What is the SECOND step in solving a two-step equation?

Back

Multiply or divide both sides by the coefficient of the variable.

Front

If you have the equation 2x + 3 = 11, what is the first step to solve for x?

Back

Subtract 3 from both sides to get 2x = 8.

Front

In the equation 2x = 8, what is the next step to find x?

Back

Divide both sides by 2 to get x = 4.

Front

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

Back

To manipulate the equation so that the variable is alone on one side.

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 check if your solution to a two-step equation is correct?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

What is the solution to the equation 3x - 5 = 16?

Back

x = 7.

Front

What is the first step to solve the equation x/4 + 2 = 5?

Back

Subtract 2 from both sides to get x/4 = 3.
