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 next step you should take?

14x + 8 = -3 - 7x

• Collect the variables (letters) on the left side

• multiply -7 to both sides

• add 14x to both sides

• subtract 7x to both sides

Solve for x:

2x - 5 = 3x + 4

• x = 6

• x = -9

• x = -18/13

• x = 10/3

5w + 5 = 8w - 10

• -5

• -2

• 2

• 5

Solve the equation

4x - 5x + 9 =5x - 9

• x = -3

• x = 9

• x = 3

• x = -9

8x - 8 = -4x + 16

• 8

• 16

• 24

• 2

2 + (¹∕₄)a = 10

• a= 32

• a= 48

• a= 2

• a= -2
