Solve 2 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

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 appear in the equation.

Front

Solve: 7 - 3y = 22

Back

y = -5

Front

Solve: 2x - 3 = 1

Back

x = 2

Front

Solve: y - 4.6 = 12

Back

y = 16.6

Front

What is the first step to solve the equation 5y + 3 = 18?

Back

Subtract 3 from both sides to get 5y = 15.

Front

What is the second step to solve the equation 5y = 15?

Back

Divide both sides by 5 to get y = 3.

Front

Solve: ⅔x - 5 = 7

Back

x = 18

Front

What does it mean to 'balance' an equation?

Back

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

Front

What is the solution to the equation 4x + 2 = 18?

Back

x = 4.
