Question. 49
a = 3 is a solution of the equation 2a – 1 = 5
Answer:
true
Detailed Answer with Explanation:
Check by substitution:
- Given equation: (2a - 1 = 5)
- Put (a = 3).
Left Hand Side (LHS):
(2a - 1)
(= 2 imes 3 - 1)
(= 6 - 1)
(= 5)
Right Hand Side (RHS):
(5)
Compare:
LHS (= 5) and RHS (= 5)
Conclusion: LHS = RHS, so the equation is satisfied when (a = 3). Therefore, the statement is true.
