Question -
Answer -
(i) x + 3 = 0
LHS = x + 3
By substituting thevalue of x = 3
Then,
LHS = 3 + 3 = 6
By comparing LHS andRHS
LHS ≠ RHS
∴No, the equation isnot satisfied.
(ii) x + 3 = 0
LHS = x + 3
By substituting thevalue of x = 0
Then,
LHS = 0 + 3 = 3
By comparing LHS andRHS
LHS ≠ RHS
∴No, the equation isnot satisfied.
(iii) x + 3 = 0
LHS = x + 3
By substituting thevalue of x = – 3
Then,
LHS = – 3 + 3 = 0
By comparing LHS andRHS
LHS = RHS
∴Yes, the equation issatisfied
(iv) x – 7 = 1
LHS = x – 7
By substituting thevalue of x = 7
Then,
LHS = 7 – 7 = 0
By comparing LHS andRHS
LHS ≠ RHS
∴No, the equation isnot satisfied
(v) x – 7 = 1
LHS = x – 7
By substituting thevalue of x = 8
Then,
LHS = 8 – 7 = 1
By comparing LHS andRHS
LHS = RHS
∴Yes, the equation issatisfied.
(vi) 5x = 25
LHS = 5x
By substituting thevalue of x = 0
Then,
LHS = 5 × 0 = 0
By comparing LHS andRHS
LHS ≠ RHS
∴No, the equation isnot satisfied.
(vii) 5x = 25
LHS = 5x
By substituting thevalue of x = 5
Then,
LHS = 5 × 5 = 25
By comparing LHS andRHS
LHS = RHS
∴Yes, the equation issatisfied.
(viii) 5x = 25
LHS = 5x
By substituting thevalue of x = -5
Then,
LHS = 5 × (-5) = – 25
By comparing LHS andRHS
LHS ≠ RHS
∴No, the equation isnot satisfied.
(ix) m/3 = 2
LHS = m/3
By substituting thevalue of m = – 6
Then,
LHS = -6/3 = – 2
By comparing LHS andRHS
LHS ≠ RHS
∴No, the equation isnot satisfied.
(x) m/3 = 2
LHS = m/3
By substituting thevalue of m = 0
Then,
LHS = 0/3 = 0
By comparing LHS andRHS
LHS ≠ RHS
∴No, the equation isnot satisfied.
(xi) m/3 = 2
LHS = m/3
By substituting thevalue of m = 6
Then,
LHS = 6/3 = 2
By comparing LHS andRHS
LHS = RHS
∴Yes, the equation issatisfied.
