Sometimes V-12, sometimes 12-V what does it refer?

Can you me proper sign convention in nodal analysis?

(VA-12)/49+VA/24+(VA-6)/80 = 0.
0.02(VA-12)+0.04VA+0.0125(VA-6) = 0.
VA(approx) = 4.3v.
0.02(VA-12)+0.04VA+0.0125(VA-6) = 0.
VA(approx) = 4.3v.

Applying nodal analyses at node A.
I1 = (I2+I3).
(12-Va)/49 = Va/24+(Va-6)/80.
(Va = 4.289).
I1 = (I2+I3).
(12-Va)/49 = Va/24+(Va-6)/80.
(Va = 4.289).

@Krishna.
Is right according to nodal analysis. The algebraic sum of currents in a network of conductors meeting at a point is zero.
Here we take i=v/r.

For nodal analysis voltage source must be converted to current source right?

STEPS FOR NODAL ANALYSIS.
STEP 1: Choose the nodes and node voltages to be obtained.
STEP 2: Choose the currents preferably leaving the node at each
branch connected to each node.
STEP 3: Apply Kirchhoff's current law at each node with proper sign
convention.
Now apply the procedure suggested by our friends.
