i1 = 9/150,
i2 = 12/150,
vb = i1*74 + i2*76,
vb = 10.52.

Vr 9V = (76k/150k) .9 = 4.56.
Vr 12V = (74k/150k) .12 = 5.92.
So, 4.56 + 5.92 = 10.48.

The answer should be approximately 1.5 volts the power sources positive facing positive cancel out resulting in a source voltage of 3 volts.

Use Millman's Theorem:

This is used to find the voltage across parallel branches with different voltage sources.
Vb = (9+73K)+(12+76K)/(1/73K)+(1/76K).
