Question 49

Check by substitution:

1. Given equation: (2a - 1 = 5)
2. 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.
