Answer 1

Answer:

Let the number be x.

A/Q

$\frac{2}{3} x + 9 = 19 \\ = \frac{2x + 27}{3} = 19 \\ = 2x + 27 = 19 \times 3 \\ = 2x = 19 \times 3 - 27 \\ = 2x = 30 \\ = x = \frac{30}{2} = 15$

Answer 2

Answer:

Let the number be n

As per given condition

2n/3 + 9 = 19

2n/3 = 19-9

2n/3 = 10

2n = 30

n = 15

Number is 15
