2-Step Equations

Front

What is a 2-step equation?

Back

A 2-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in a 2-step equation?

Back

To isolate a variable, perform the inverse operations in the reverse order of how they appear in the equation.

Front

Solve for x: -1x + 10 = 5

Back

x = 5

Front

Solve for x: 12 = 5x + 17

Back

x = -1

Front

Solve for x: -3x + 8 = -1

Back

x = 3

Front

Solve for x: -8x + 3 = 27

Back

x = -3

Front

Solve for x: 14 = 6x - 4

Back

x = 3

Front

What is the first step to solve the equation 2x + 3 = 11?

Back

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

Front

What is the second step to solve the equation 2x = 8?

Back

Divide both sides by 2 to get x = 4.

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means performing the same operation on both sides to maintain equality.
