Solving Equations Without Integers

What is the correct step to solve for the variable?

• add 5 to both sides

• add 15 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

• 5

• -5

• 1

• -1

Which equation matches the table?

• y = x + 5

• y = 5x

• y = x - 5

• x = y - 5

What is the missing number in the table?

• 12

• 10

• 14

• 13

• 2

Translate: Six fewer than twice a number is four.

• 6 - 2x = 4

• 2x - 6 = 4

• x² - 6 = 4

• 6 - x² = 4

• 7

• -16

• 4

• -15

Solve for k:

• k = 32

• k = 12

• k = 44

• k = 8

Which of the following would be an incorrect first step? 1/4 x + 9 = 3/4 x - 2 NOTE: Only one is incorrect though others might not be what WE would do but still could work.

• subtract 1/4x from both sides

• subtract 3/4x from both sides

• multiply everything through by 4

• add 1/4x and 3/4x
