Hello

Please could someone rearrange and show the steps for solving simultaneous equations for 2 unknowns, please? The unknowns are r and theta.

Equation 1 is

IB = (2r^2 / (17 x 10^3) x Na) (21 - 11sin^2 theta)

Equation 2 is

IB* = (r^2 / (5 x 10^3) x Na) (21 - 8sin^2 theta)

Thank you very much.

Kind regards,

A
