Basic Two-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 for a: -3a + 8 = 14

Back

a = -2

Front

Solve for x: 62 = 12x + 2

Back

x = 5

Front

Solve for a: 33 = 4a - 7

Back

a = 10

Front

Solve for x: 11x - 8 = 3

Back

x = 1

Front

Solve for x: 3 = 5x - 12

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 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 inverse operation of addition?

Back

The inverse operation of addition is subtraction.
