Answer 1

Question :

find the numbers such that one is twice of the other and their difference is 15

Answer :

• let the number be "x"

• therefore the other is twice it = 2x

• their difference is 15

Equation :

$\longrightarrow\bf{ 2x - x = 15}$

$\longrightarrow\bf{ x = 15}$

• Therefore one number is x

$\longrightarrow\bf{ x = 15}$

• The other number is 2x

$\longrightarrow\bf{ 2x = 2\times 15}$

$\longrightarrow\bf{ 30 }$

• Therefore the other number is 30 .
