Question

if the product of 6 and an interger n is increased by 13 the result is -14 what is the value of n

Answer 1

Here the unknown number is n . Product of 6 and n is 6n. And 6n is increased by 13 that is 6n +13. And the result is -14 , that is

6n+13=-14

We need to get rid of 13, so we subtract 13 to both sides, that is

6n = -14-13

6n =-27

Now we need to get rid of 6,and for that we divide both sides by 6, that is

n = -27/6

And that's the required value of n .
