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: 2x - 4 = 10

Back

x = 7

Front

Solve: x/5 - 13 = 20

Back

x = 165

Front

Solve: 15 = 2a + 7

Back

a = 4

Front

Solve: 9 + 3x = 10

Back

x = 1/3

Front

Solve: x/3 + 10 = 15

Back

x = 15

Front

What is the first step to solve the equation 3x + 5 = 20?

Back

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

Front

What is the second step to solve the equation 3x = 15?

Back

Divide both sides by 3 to get x = 5.

Front

What does it mean to 'balance' an equation?

Back

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