Answer 1

Answer:

x=1

Step-by-step explanation:

let the number be x

then-

x-2/9*9=7x

9x-2/9*9=7x

9x-2=7x(9 and 9 got cancelled)

9x=7+2

9x=9

x=1

Answer 2

Question:-

• Krishna thinks of a number and subtracts 2 by 9 from it. He multiplies the result by 9.The result obtained now is seven times the same number he thought of.What is the number?

To Find:-

• Find the number.

Solution:-

• Let the unknown number be x

According to the Question:-

$\dashrightarrow\sf \: \bigg [ \bigg ( x - \dfrac { 2 } { 9 } \bigg ) \times 9 \bigg ] = 7x$

$\dashrightarrow\sf \: \bigg ( \dfrac { 9x - 2 } { 9 } \times 9 \bigg ) = 7x$

$\dashrightarrow\sf \: 9x - 2 = 7x$

$\dashrightarrow\sf \: 9x - 7x = 2$

$\dashrightarrow\sf \: 2x = 2$

$\dashrightarrow\sf \: x = \dfrac { 2 } { 2 }$

$\dashrightarrow\sf \: x = 1$

Hence ,

• The number is 1.
