Answer 2

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

Given,

$\textbf{\underline{Sum\;of\;two\;number\;is\; -12}}$

$\textbf{\underline{Difference\;is\;1}}$

Assume

Number be x and y respectively

So,

x + y = -12 ....... (1)

x - y = 1 ........... (2)

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

x + y + (x - y) = -12 + 1

x + y + x - y = -12 + 1

2x = -12 + 1

2x = -11

$\rm \: \: \: \: \: \: \: \: \:x=\dfrac{-11}{2}$

Hence,

$\rm \: \: \: \: \: \: \: \: \: First\;number=\dfrac{-11}{2}$

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

x + y = -12

(-11/2) + y = -12

y = -12 + (11/2)

y = -13/2

$\rm \: \: \: \: \: \: \: \: \: First\;number=\dfrac{-13}{2}$
