Question

9. The sum of 10 and 7 times a number is 59. What is the
number? (Use n as the variable.)

Answer 1

10+7n=59
7n=59-10
7n=49
n=49/7
n=7

Answer 2

7

Explanation:

Let,

The number be = n

According to the question,

First 7 times of n = 7n

Sum of 10 and the number = 7n + 10

Said that,

The sum of 10 and 7 times of the number is 59.

Therefore,

By the problem ,

=> 7n + 10 = 59

=> 7n = 59 - 10

=> 7n = 49

`= > n = (49)/(7)`

=> n = 7

Hence,

The required number is 7 (Ans)
