Question

Meena's mother is 26 years older than Meena. After 4 years, the mother's age will be 3 times Meena's age at that time. Meena's present age is:

For what value of k is x = 3 a solution of 2x + k = 5x - 4?

Assertion (A): The equation 2(x + 3) = 2x + 6 has exactly one solution. Reason (R): If both sides of an equation become the same expression on simplifying, the equation is true for every value of the variable.

x = 5 is the solution of 2x - 3 = x + 2.
