take me seven times over

to reach a triple century
you still need forty​

Answer 1

Answer:

The answer is 260. It is correct

Answer 2

Step-by-step explanation:

number = x

take me seven times over = multiply by 7 = 7 × x = 7x

and add a fifty = 7x + 50

triple century = 300 ( 1 century = 100 )

So to reach 300 we still need a 40 means you need to add 40 to get 300 or a triple century

so , the equation will be :

7x + 50 + 40 = 300

7x + 50 - 40 = 300 - 40

7x + 50 = 260

7x - 50 = 260 - 50

7x = 210

x = 210 ÷ 7

x = 30

therefore , the numerical value of x is 30 .
