Question

yadi a+b=-2 aur a-b=12to B ka man gyat karen?​

Answer 1

HELLO DAER FRIEND

a + b = - 2 ....(1)

a - b = 12 ....(2)

(1) + (2)

a + b + a - b = - 2 + 12

2a = 10

$\large{ a = \frac{ \large{10}}{ \large{2}} }$

$\large \boxed{a = 5}$

putting the value of a on (1)

a + b = - 2

5 + b = - 2

b = - 2 - 5

$\large \boxed{b = - 7}$

so,

$\boxed{ \large \boxed{ \huge{\boxed{a = 5} \: \: \: \: \: \boxed{b = -7}}}}$
