Question

Fifteen less than eight tiles a number is equal to to 11 more than six times the number. What is the number ?

Answer 1

The number
`=13`.

Explanation:

Lets assume that the number be
`x` .

So accordingly

We have fifteen less than eight times a number that is
`8(x)-15`

And we have,

Eleven more than six times of that number that is
`6(x)+11`

Equating both.

`8(x)-15` =
`6(x)+11`

Subtracting
`6(x)` and adding
`15` both sides of the equation.

`8(x)-6(x) = 15+11`

`2(x)) = 26`

So finally the number
`=13`.

Dividing both sides with 13.

`x = (26)/(2) =13`
