Let the other be x,

According to the question,

A number is 5 times the other number .

So, the number will be 5x .

7 is added to both the numbers in one of the new number becomes thrice the other new number .

➝ 3 ( x + 7 ) = 5x + 7

➝ 3 x + 21 = 5x + 7

➝ 3x - 5x = 7 - 21

➝ -2x = -14

➝ x = $\cancel{\dfrac{ - 14}{ - 2}}$

➝ x = 7

Ths other = x = 7

the number = 5x = 5 × 7 = 35
