Question

verify that a+b=b+a where a=3/4,b=-3/5​

Answer 1

Step-by-step explanation:

a=3/4, b=-3/5

LHS:

a+b = 3/4-3/5

= 15-12/20

= 3/20

RHS:

b+a= -3/5+3/4

= -12+15/20

=3/20

therefore, LHS=RHS. Thus proved.

Answer 2

Step-by-step explanation:

a=3/4,b=3/5

3/4+3/5= 15/20+12/20= 27/20

3/5+3/4=12/20+15/20=27/20

Thus,a+b=b+a proved
