Use the node voltage method to find the voltage at point A w

Use the node voltage method to find the voltage at point A with respect to grand.

APPLY NODAL ANALYSIS AT NODE \'A\'.

(VA-30)/82+(VA-40)/68+VA/(100+47)=0

VA[1/82+1/68+1/147]=(40/68)+(30/82)

VA[(147*68+82*147+82*68)/(82*68*147)]=(40*82+30*68)/(68*82)

VA=[147(40*82+30*68)]/[147*68+82*147+82*68]=28.308 VOLTS.
