One Step Addition and Subtraction

What is the solution of the equation? 
8 = x + 1

• 9

• 7

• -7

• -9

Solve for the variable.
x - 5 = 20

• x = -25

• x = -15

• x = 15

• x = 25

What what is the inverse operation of subtraction?

• addition

• subtraction

• multiplication

• division

W + 32 =26

• W=58

• W=-58

• W=-6

• W=6

How do you solve this equation?

• add 21 to both sides

• add 6 to both sides

• subtract 21 from both sides

• subtract 6 from both sides

Solve the equation:
20.5 = x + 4

• 16.5

• 16.05

• 24.5

• 24.05

5 less than a number is 15.

• x - 5 = 15

• 5 - x = 15

• 15 - x = 5

Solve the equation
1/4 + x = 7/8

• 1

• 6/7

• 5/8

• 2/3

Solve the equation. 
  z- 2⅓= 1⅔

• z= 4

• z= 3

• z= 2⅓

• z= 3⅔

What property states that you can add the same number to both sides of an equation and the two sides will remain equal.

• distributive property

• addition property of equality

• commutative property

• associative property
