How will you explain how this problem was solved?

An enclosed chamber contains a gas that is cooled while stirred by a wheel. The work applied on the fluid is one-hundred fifty kilo-Joule. The final internal energy of the fluid is seven-hundred fifty kilo-Joule with a heat of nine-hundred Joule. Determine the initial internal energy. Given : W = -150 kJ U2 = 150 k) Q = -900 J Required : Solution : Q = ut W Q = (u2 - u,) + w u, = u2 + w - Q u, = 150 kJ + (- 150 kJ) - (- 900 8 x 10008 U, : 600. 9 kj
