Answer 1

Answer:

hi i cant solve all the parts for you but i can explain you how it has to be done

suppose in the first part you have the following details:

x + 3 = 0    is equation

and x = 3 is your value

so in the equation put the value like:

if x = 3 then

3 + 3 = 9 ans

but we have told that x + 3 = 0 so it is not correct

likewise if the solution is same then you can say that LHS = RHS

hence verified

if not then LHS is not = RHS

hope it's helpful for you
