By KVL/Mesh analysis you can get that the currents: I1 = 0.09 A, I3 = 0.01 A, & I2=0.1 A. You can use any of these currents and perform nodal analysis on point A.
Using I1:
(19-Va)/100 = 0.09A ; Va = +10V.
Using I2:
(Va-0)/100 = 0.1A; Va = +10V.
Using I3:
(19-Va)/900 = 0.01; Va = +10V.
Using I1:
(19-Va)/100 = 0.09A ; Va = +10V.
Using I2:
(Va-0)/100 = 0.1A; Va = +10V.
Using I3:
(19-Va)/900 = 0.01; Va = +10V.

(19-Va)/100 = Va/100+(Va-19)/900,
The value of Va will be found from here.
Va = 10.
The value of Va will be found from here.
Va = 10.
