What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

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 final answer to

10 + 2n = 8n - 2n + 10 ?

• 12

• 5

• 0

• -15

What is the first step you should take to solve this problem?

-3(x - 2) = -8 +9b

• add 8 to both sides

• subtract 9b from both sides

• Distribute -3 to the x and -2
