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 c: 3c + 5 = 23

Back

c = 6

Write an equation for this scenario: 331 students went on a field trip. Six buses were filled and 7 students traveled in cars.

Back

6x + 7 = 331

Front

Solve for x: 2x - 3 = 1

Back

x = 2

Front

Solve for a: 33 = 4a - 7

Back

a = 10

Front

Solve for y: 12y - 8 = 30.4

Back

y = 3.2

Front

What is the first step to solve the equation 4x + 8 = 20?

Back

Subtract 8 from both sides to get 4x = 12.

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

If you have the equation x/2 = 5, how do you solve for x?

Back

Multiply both sides by 2 to get x = 10.
