## Homework Statement

I am trying to find ix and iy.

Here is the figure

## The Attempt at a Solution

Node 1

-3 + V1/0.2 + (V1-V2/0.5) = 0

-.06 + 0.1V1 +0.2V1 - 0.2V2 =0

-.06 + 0.3V1 -0.2V2 = 0

Node 2

-6 +( V2 - V1/0.1) + V2/0.5=0

-0.3 + 0.5V2 - 0.5V2 + V2/0.5=0

0.6V2 = 0.5V1 +0.3

V2= 0.5V1 + 0.3 / 0.6

Substituting V2 in V1

0.3V1 - 0.2( (0.5V1 + 0.3 )/ 0.6)=0

.14 V1 =.159

V1 = 1.13

Substituting V1 back in V2

V2 = 0.5(1.13 + 0.3)/ 0.6 = 1.19 V

ix = 1.19-1.13 / .2 = .3 ?

iy = V2 / R = 1.19/1 = 1.19 ?

P.S The answers are iy = -1.5 ix = 1.5.

Where exactly am I going wrong with this? I don't think I missed any variables , etc.Is there a conceptual mistake ?Please help me out here. Thanks.
