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: 33 = 4a - 7

Back

a = 10

Front

Solve for c: 3c + 5 = 23

Back

c = 6

Front

Solve for x: 2x - 3 = 1

Back

x = 2

Front

Solve for p: 7p + 9 = 40.5

Back

p = 4.5

Front

Solve for x: 3x - 7 = 32

Back

x = 13

Front

What is the first step to solve the equation 4x + 8 = 24?

Back

Subtract 8 from both sides to get 4x = 16.

Front

What is the second step to solve the equation 4x = 16?

Back

Divide both sides by 4 to get x = 4.

Front

What does it mean to 'balance' an equation?

Back

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