Two-Step Equations G/K

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 in solving the equation x + 5 = 10?

Back

Subtract 5 from both sides to isolate x.

Front

What is the solution to the equation 2x = 8?

Back

Divide both sides by 2 to find x = 4.

Front

If x - 3 = 7, what is x?

Back

Add 3 to both sides to find x = 10.

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means keeping both sides equal by performing the same operation on both sides.

Front

Solve for x: 3x + 6 = 15.

Back

Subtract 6 from both sides to get 3x = 9, then divide by 3 to find x = 3.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.

Front

What is the inverse operation of multiplication?

Back

The inverse operation of multiplication is division.

Front

If 5x - 10 = 0, what is x?

Back

Add 10 to both sides to get 5x = 10, then divide by 5 to find x = 2.
