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 c: 2c + 2 = 10

Back

c = 4

Front

Solve for t: -3t + 4 = 19

Back

t = -5

Front

Solve for a: -24 - a = -15

Back

a = -9

Front

Solve for d: 2d + 7 = 9

Back

d = 1

Front

Solve for e: 22 = 4 + 6e

Back

e = 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 is the second step to solve the equation 2x = 8?

Back

Divide both sides by 2 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.
