S.no.




Equation




Value




Say, whether the equation is satisfied. (yes/No)




(i)




x + 3 = 0




x = 3



 put x = 3 in the equation.


L.H.S. = 3 + 3 = 6 ≠ RHS


 Thus, the answer is No i.e. the equation is not satisfied.


 


(ii)




x + 3 = 0




x = 0


 

 put x = 0 in the given equation.


L.H.S. = 0 + 3 = 3 ≠ RHS


Thus, the answer is No i.e. the equation is not satisfied.




(iii)




x + 3 = 0




x = -3


 

 put x = -3 in the given equation.


L.H.S. = -3 + 3 = 0 = RHS


Thus, the answer is Yes i.e. the equation is satisfied




(iv)




x - 7 = 1




x = 7


 

put x = 7 in the given equation.


L.H.S. = 7 – 7 = 0 ≠ RHS


Thus, the answer is No i.e. the equation is not satisfied.




(v)




x - 7 = 1




x = 8


 

 put x = 8 in the given equation.


L.H.S. = 8 – 7 = 1 = RHS


Thus, the answer is Yes i.e. the equation is satisfied.




(vi)




5x = 25




x = 0


 

put x = 0 in the given equation.


L.H.S. = 5(0) = 0 ≠ RHS


Thus, the answer is No i.e. the equation is not satisfied




(vii)




5x = 25




x = 5


 

 put x = 5 in the given equation.


L.H.S. = 5(5) = 25 = RHS


Thus, the answer is Yes i.e. the equation is satisfied




(viii)




5x = 25




x = -5


 

put x = -25 in the given equation.


 


L.H.S. = 5(-5) = -25 ≠ RHS


 


Thus, the answer is No i.e. the equation is not satisfied.




(ix)







m = -6


 

Put m = -6 in the given equation.


 


L.H.S. = = -2 ≠ RHS


 


Thus, the answer is No i.e. the equation is not satisfied.




(x)







m = 0


 

put m = 0 in the given equation.


L.H.S. = = 0 ≠ RHS


Thus, the answer is No i.e. the equation is not satisfied.




(xi)







m = 6


 

put m = 6 in the given equation.


L.H.S. = = 2 LHS = RHS


Thus, the answer is No i.e. the equation is not satisfied.
