Solving 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 are applied.

Front

Solve for a: 6 - 3a = 21

Back

a = -5

Front

Solve for x: -5x - 2 = 48

Back

x = -10

Front

What is the first step to solve the equation -4x + 1 = 21?

Back

Subtract 1 from both sides to get -4x = 20.

Front

Solve for x: -4x + 1 = 21

Back

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.

Front

Solve for n: -54 = -4n + 2

Back

n = 14

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable, allowing us to isolate it.
