Calculate the voltmeter reading for this circuit with 2 sources and 2 resistors

Homework Statement

Please see below

Relevant Equations

V = I.R

I find the current first, which is 2 A. Then the voltmeter reading would be 10 V - 1 x 2 = 8 V.

But the answer is 12 V.
I don't understand why it should be 10 + 1 x 2 = 12 V

Thanks

I agree with your answer. It obviously cannot be more than 10V.

Yes, I agree, 8V is correct.
