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.
