Explain Steps in Solving Simple Equations

y + 8 = 45

• y = 8

• y = 37

• y = 45

• y = 27

25 + b = 97

• b = 97

• b = 62

• b = 25

• b = 72

The equation is 14 + x = 21. What is the value of x?

3x + 2 = 8. What is the value of x?

• x = 3

• x = 2

• x = 6

• x = 8

• x = 5

Which operation should be used to solve 3x = 36 for x?

• add 3 to both side

• subtract 3 from both side

• divide both sides by 3

• multiply both sides by 3

How would the inverse operation of addition be used to solve this equation? 36 + m = 5

• Divide both sides of the equation by 2

• Multiply both sides of the equation by 2

• Subtract 2 from both sides of the equation

Which of the following statements describes how to use an inverse operation to solve the equation c + 6 = 16

• . Multiply both sides of the equation by six because multiplication is the inverse operation of addition.

• . Subtract six from both sides of the equation because subtraction is the inverse operation of addition.

• C. Add six to both sides of the equation because addition is the inverse operation of subtraction.

• D. Divide both sides of the equation by six because division is the inverse operation of addition

m -5 = -10

• m= 15

• m= 50

• m = -5

• m= 2
