Question

The difference of 8 less a number n, multiplied by twelve, is equal to 3 more than the number. Which of the following equations can be used to find the missing number?

Answer 1

Answer:

• The equation that can be used to obtain the missing number is (n - 8 )12 = 3 + n

• The missing number is 9

Step-by-step explanation:

The missing number is given as 'n'

The equation that can be used to obtain the missing number is calculated as follows;

(n - 8 )12 = 3 + n

The equation above can be used to obtain the missing number 'n'

The missing number 'n' is calculated as follows;

(n - 8 )12 = 3 + n

12n - 96 = 3 + n

12n - n = 3 + 96

11n = 99

n = 99/11

n = 9

Therefore, the missing number is 9

Answer 2

Answer:

The equation that can be used to find the missing number is 96 - 12n = 3 + n

Step-by-step explanation:

The difference of 8 less a number n

This is 8 - n

Multiplied by twelve

This is:

12(8 - n) = 96 - 12n

Is equal to 3 more than the number.

96 - 12n = 3 + n

The equation that can be used to find the missing number is 96 - 12n = 3 + n
