Working with Equations

Is the equation below True or False?

64 - 37 = 59 - 31

• True

• False

Which side of a false equation has the greater value?

• the left side

• the right side

• The two sides have the same value.

• It depends on the equation.

Tell whether the equation is True or False.

22 x 2 = 11 x 4

• True

• False

Tell whether the equation is True or False.

15  $\div$  5 = 30  $\div$  10

• True

• False

Which statement tells the reasoning you can use to find the unknown number, n, in this equation?

n + 79 = 30 + 74

• Add 5 to 30 because 79 is 5 more than 74.

• Add 30 to 74 because that is the value of the right side.

• Subtract 5 from 30 because 79 is 5 more than 74.

• Subtract 30 from 79 because 79 is 30 more than the value of the right side.

Is the equation True or False?

58 + 30 = 88 - 5

• True

• False

Is the equation True or False?

21 x 5 = 3 x 28

• True

• False

Is the equation True or False?

20 + 52 = 14 + 60

• True

• False

Which statement is NOT true about the following equation?

8 + 57 = n + 60

• The value of n must be less than 8.

• You can find n by adding 8 + 57.

• Both sides of the equation must equal 65.

• 57 is 3 less than 60, so 8 is 3 more than n.

Which side of a true equation is greater?

• the left side

• the right side

• The two sides have the same value.

• It depends on the equation.
