Question

Eight less than 1/3 a number n is -13

Answer 1

1/3n - 8 = -13 <== ur equation
1/3n = -13 + 8
1/3n = - 5
n = -5 * 3
n = -15

check..
1/3(-15) - 8 = -13
-5 - 8 = -13
-13 = -13 (correct)

so the number (n) = -15

Answer 2

Answer: The required value of n is -15.

Step-by-step explanation: Given that eight less than one-third of a number n is -13.

We are to find the value of n.

According to the given information, the equation for n can be written and solved as follows :

`(1)/(3)* n-8=-13\\\\\\\Rightarrow (n-24)/(3)=-13\\\\\Rightarrow n-24=-13*3\\\\\Rightarrow n-24=-39\\\\\Rightarrow n=-39+24\\\\\Rightarrow n=-15`

Thus, the required value of n is -15.
