What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides

• Add the 2a and a 

• Distribute 4 to a and -5

• Distribute -4 to a and -5

What is the error?

• Adding 2x to 3x

• Subtracting 5 from both sides

• Adding 2x to -2x

• Dividing by 5 on both sides

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

Simplify the following expression:

-6x + 4(x - 3)

• -2x - 12

• 10x + 12

• -10x - 12

• -2x + 12

8a + 6 + 1+ 8a - 3b + b

• 16a + 4b + 7

• 16a - 3b + 7

• 16a - 2b + 7

• 64a + -3b + 7

4a + 9 + a

• 5a + 9

• 14a

• 3a + 9

• 5a - 9

3(2x + 4) + 4(x - 5)

• 10x + 32

• 10x - 8

• 9x - 8

• 10x - 1
