Answer To Your Question:
(i)no
(ii)no
(iii)yes
(iv)no
(v)yes
(vi)no
(vii)yes
(viii)no
(ix)no
(x)no
(xi)yes
Step-by-step explanation:
(i)x+3=0; x=3
Ans) As x =3
The equation will become 3+3=6
=6≠0
∴The answer is NO.
(ii)x+3=0; x=0
Ans)As x =0
The equation will become 0+3=3
=3≠0
∴The answer is NO.
(iii)x+3=0; x= -3
Ans) As x = -3
The equation will become -3+3=0
∴The answer is YES.
(iv)x-7=1; x=7
Ans) As x =7
The equation will become 7-7=0
=0≠1
∴The answer is NO.
(v)x-7=1; x=8
Ans) As x =8
The equation will become 8-7=1
∴The answer is YES.
(vi)5x=25; x=0
Ans) As x =0
The equation will become 5×0=0
=0≠25
∴The answer is NO.
(vii)5x=25; x=5
Ans) As x =5
The equation will become 5×5=25
∴The answer is YES.
(viii)5x=25; x= -5
Ans) As x = -5
The equation will become 5×-5= -25
= -25≠25
∴The answer is NO.
(ix) m/3=2;m= -6
Ans) As m= -6
The equation will become -6/3= -2
= -2≠2
∴The answer is NO.
(x) m/3=2;m=0
Ans) As m=0
The equation will become 0/3=0
= 0≠2
∴The answer is NO.
(xi) m/3=2;m=6
Ans) As m=6
The equation will become 6/3=2
∴The answer is YES.
