below is the circuit given for node analysis. now using kcl we come up with following equations

GAE1 + G3(E1 - E2) = I1 (1)

GBE2 - G3(E1 - E2) = I2 (2)

i used plus in equation 2 before G3(E1 - E2) but my friend told me that it should be negative.i am too much confused about this minus sign before G3(E1 - E2) . i dont know why it isnt positive the way it is in equation 1

please elaborate as i couldnt understand the basic logic behind this
