Hey Everyone,

Unfortunately I'm having a tough time trying to figure out this problem:

Equation 1: $\displaystyle 16\times I_1 = 100\times I_1^2 + 300\times I_2^2 + 0.02^2\times R$

Equation 2: $\displaystyle I2 = I1 - 0.02$

Equation 3: $\displaystyle I1 = 0.015 + \frac{1.5 + 0.02R}{75}$

I'm supposed to merge everything together and solve for R, but my calculations go right off the drawing board. I'd appreciate any help!

Thanks!
