Question

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

Answer 1

Answer:

7

Step-by-step 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

$= > n = \frac{49}{7}$

=> n = 7

Hence,

The required number is 7 (Ans)

Answer 2

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