Solve the equation:
4x - 5x + 9 = 5x - 9

• x = -3

• x = 9

• x = 3

• x = -9

What is the next step you should take?

1 + 4n = 10 - 14n

• Collect the variables (letters) to the left

• add 1 from both sides

• subtract 14n to both sides

What is the next step you should take?

1 + 18n = 33

• subtract 1 to both sides

• collect the numbers to the right

• add 1 to both sides

• multiply 18 to both sides
