hlooo dear...!!!

Let the number be x.
(7x + 50) + 40 = 300
7x + 90 = 300
7x = 300 − 90 (Transposing 90 to R.H.S.)
7x = 210
Dividing both sides by 7,
x = 30
Therefore, the number is 30.

Heya user !!!

Here's the answer you are looking for

Let the number be a

The question says take me 7 times over , and add a fifty, to reach a triple century , you still need forty


So, 7a + 50 + 40 = 300

7a + 90 = 300

7a = 300 - 90 = 210

a = 210/7 = 30


Therefore, the number is 30.
