Question

When 18 is subtracted from six times a certain number ,the result is -42 what is the number

Answer 1

The value for such given number is -4.

Explanation:

Let the given number = m

So, according to the question: 6 m - 18 = -42

Now, solving for the value of m,

6m - 18 = -42 ⇒ 6m = -42 + 18

⇒ 6m = -24

or, m= -24/ 6 = -4

So, m = -4

Hence the value for such number is -4.
