Question

find the unknown number when one third of the number is added to 9 the sum becomes 19 ​

Answer 1

Answer:

x/3 + 9 = 19

Taking LCM,

(x + 27)/3 = 19

x + 27 = 57

x = 57 - 27

x = 30

Verification :-

30/3 + 9 = 10 + 9 = 19

Hope it helps.....

Answer 2

$\huge\underline\mathfrak\red{Answer:}$

$\bf{Let \: the \: number \: be \: = \: x}$

$\frac{x}{3} + 9 = 19$

$\frac{x}{3} = 19 - 9$

$\frac{x}{3} = 10$

$x = 10 \times 3$

$x = 30$
