Question

Rohan thinks of a number and substracts 2/3 from it and multiplies the result by 9. The product now obtained is 7 times the number he thought of. What is the number?​

Answer 1

Answer:

Let the number be x.

(x-2/3)×9=7x

9x - 6=7x

2x=6

x=3

The number is 3

Answer 2

Answer:

3 is the number

Step-by-step explanation:

Let the number be X

According to th question

x- $\frac{2}{3}$ ×9=7x

$\frac{x}{1}$ - $\frac{2}{3}$ × 9=7x

$\frac{3x-2}{3}$  × 9= 7x

(3x-2)×3= 7x

9x-6=7x

9x-7x=6

2x=6

x=$\frac{6}{2}$=3
