A number, n, is added to 15 less than 3 times itself. The result is 101. Which equation can be used to find the value of n? 3n – 15 + n = 101 3n + 15 + n = 101 3n – 15 – n = 101 3n + 15 – n = 101

The correct option is;

3·n – 15 + n = 101

Step-by-step explanation:

Here we have,  a question with a word problem

the equation stated is n + (3 × n - 15) = 101

We analyze each of the options to find the correct one as follows;

(a) 3·n – 15 + n = 101

The above equation is equivalent to the equation in the solution above hence it is correct

(b) 3·n + 15 + n = 101

Here 15 is added to 3 times n, therefore it is not correct

(c) 3·n – 15 – n = 101

Here n is subtracted from 3·n - 15 so it is in error

(d) 3·n + 15 – n = 101

Here also n is subtracted while 15 is added so it is not correct.
