DC circuit

I calculated the voltage to be 6.25volts

20v - (1000x0.0055) - (1500x0.0055) = 6.25

Can someone tell me if im right or if not where ive gone wrong

Thankyou

I think it;s a valid method but your rounding is a bit wonky - if you want to give an answer to 3 sig figs you need to be using 3 sig figs for your current and any other intermediate values.

and if you're rounding properly i1-i2-i3 will be zero
