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 x + 5 = 12?

Back

Subtract 5 from both sides to isolate the variable: x = 12 - 5.

Front

What is the solution to the equation 3x = 15?

Back

Divide both sides by 3: x = 15 / 3, so x = 5.

Front

How do you solve the equation x - 4 = 10?

Back

Add 4 to both sides: x = 10 + 4, so x = 14.

Front

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

Back

Isolating the variable means to get the variable alone on one side of the equation.

Front

What is the solution to the equation 2x + 3 = 11?

Back

First, subtract 3 from both sides: 2x = 8. Then divide by 2: x = 4.

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, helping to isolate it.

Front

What is the solution to the equation 5x - 2 = 18?

Back

Add 2 to both sides: 5x = 20. Then divide by 5: x = 4.

Front

How do you check your solution for the equation x + 7 = 15?

Back

Substitute 8 back into the equation: 8 + 7 = 15, which is true.

Front

What is the solution to the equation 4x = 28?

Back

Divide both sides by 4: x = 28 / 4, so x = 7.
