Question

Twelve times of a number decreased by lo is equal to 14. write this in a mathematical sentence and find the number​

Answer 1

12n-10=14, n=2

Explanation:

( Twelve times of a number decreased by 10 is equal to 14 ) This sentence can be written mathematically to be: 12n-10=14

The answer: Add 10 to both sides: 12n-10=14 > 12n-10+10=14+10 > 12n=24

Divide both sides by 12: 12n=24 >
`(12n)/(12) =(24)/(12)` > n=2
