Question

the sum of the two numbers is 18 and diffrence is 6

Answer 1

Answer: 12 and 6.

12 + 6 = 18

12 - 6 = 6

Answer 2

$\Large{\textbf{\underline{\underline{According\;to\;the\;Questions}}}}$

Given,

$\textbf{\underline{Sum\;of\;two\;number\;is\;18}}$

$\textbf{\underline{Difference\;is\;6}}$

Assume

Number be x and y respectively

So,

x + y = 18 ....... (1)

x - y = 6 ........... (2)

$\Large{\boxed{\bigstar{{Adding\;both\;Equation :-}}}}$

x + y + (x - y) = 18 + 6

x + y + x - y = 18 + 6

2x = 18 + 6

2x = 24

$\rm \: \: \: \: \: \: \: \: \:x=\dfrac{\cancel{24}}{\cancel{2}}$

x = 12

Hence,

$\Large{\boxed{\bigstar{{First\;number= 12}}}}$

$\Large{\boxed{\bigstar{{Second\;number:-}}}}$

x + y = 18

12 + y = 18

y = 18 - 12

y = 6

Therefore,

$\huge{\boxed{\sf\:{First\;number = 12\;and\;Second\;number = 6}}}$
