Question

if a=1 b=1 prove a=b

Answer 1

a = 1 ... ( 1 )

b = 1 .... ( 2 )

From 1 and 2..

a = b ( Things which are equal to equals are equal to each other )

Answer 2

we know a =1 and b=1
if we multiply a ×b =1×1=1
so we having values of a&b
a =b because we having same values of variables
1=1
hence proved..
