Question

3 less than the product of a number and 12 is 30

Answer 1

The number is 12.75.

Explanation:

12x - 3 = 30

12x = 33

x = 33/12

x = 2.75.

Answer 2

Answer: 11/ 4

Explanation:

Let the number be x , then from the statement , we have :

12x - 3 = 30

Add 3 to both sides , we have

12x = 30 + 3

12x = 33

x = 33/ 12

x = 11/4

x = 2
`(3)/(4)`

Check:

12(11/4) - 3

33 - 3

= 30
