Sum of the solutions of the equations \(3x - 2(2x-5) = 2(x+3) - 8\) and \(3x = 5x - \frac{8}{5}\) is:

This question was previously asked in
CTET 2022 Paper 2 Maths Question Paper (Jan-27-2023) (Eng-Hin-Skt)
The correct answer is

\(\frac{24}{5}\)

Solving the first equation, \(3x - 2(2x-5) = 2(x+3) - 8\) simplifies to \(3x - 4x + 10 = 2x + 6 - 8\), that is \(-x + 10 = 2x - 2\).

This gives \(-3x = -12\), so \(x = 4\).

Solving the second equation, \(3x = 5x - \frac{8}{5}\) gives \(-2x = -\frac{8}{5}\), so \(x = \frac{4}{5}\).

The sum of the two solutions is \(4 + \frac{4}{5} = \frac{24}{5}\).

Hence, the sum of the solutions is \(\frac{24}{5}\).
