Which step cannot be performed first when solving the equation

5 - 2(x - 7) = x + 1 + 3x

• Distributing -2 to (x - 7)

• Combining x and 3x

• 5 - 2

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

• add 1 to both sides

2(4k + 7) 

• 4k-9

• 4K+9

• 8k-14

• 8k+14
