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 n: 3n + 4 = 7

Back

n = 1

Solve for x: -3x - 12 = 15

Back

x = -9

Front

Solve for x: 13 = 11 - 4x

Back

x = -1/2

Front

Solve for c: 3c + 5 = 23

Back

c = 6

Front

Solve for x: -4x + 1 = 21

Back

x = -5

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.
