Explanation / Answer

suppose

I1 => X

I2 => Y

I3 => z

so

x+y - z = 0 ..................eq1

y = z-x put this into 2 eq

- 0.085* x+ 0.015*y = -2 ........eq2

- 0.085* x + 0.015 * ( z-x ) = -2   

-0.1x + 0.015 z = -2

-0.085*x - 0.850*z = -14 ..........eq3

now from

-0.1x + 0.015 z = -2    &   -0.085*x - 0.850*z = -14 put x from one to in another and we got z value then put z value in any of two than we got x value   

z = 22.1385

x = 14.2567

now put x and z in eq 1 to get y values so we got

y= -7.88177
