Practice Solving Equations and Representing Situations with Equations

Solve the equation
21 = b - 6

• b = 27

• b = 15

Solve the equation
y - 4.1 = 5.4

• y = 9.5

• y = 5.9

• y = 4.1

• y = 5.4

Solve the equation
a - 40 = 57

• 17

• 28

• 97

• 99

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

• 1

• 6/7

• 5/8

• 2/3

Solve the equation
x + 1¹/₂  = 5³/₄

• x = 4 ¹/₄

• x = 4 ⁵/₄

• x = 4 ²/₂

• x = 5

Solve the equation. 
54 = s + 34

• s= 10 

• s=20 

• s=34

• s=14

Solve for the equation
f - 22 = 36

• f= 62

• f= 14

• f=58

• f= 12

Solve the equation. 
  z- 2⅓= 1⅔

• z= 4

• z= 3

• z= 2⅓

• z= 3⅔

What property states that if you subtract the same number from both sides of an equation, the two sides will remain equal.    For example,  3+4 =  7   
               -4         -4
both sides equal 3!

• Addition property of equality

• Subtraction property of equality

• Multiplication property of equality
