Hello! I try to solve the eq1, eq2, eq3, and eq4. I simplified the 4 equations to rs1 and rs2 to get the solution t3 and t5. Then, I check the solution by subsituting Eq(14) into Eq(10). The result is right. The rs1 equation was found by numerical tests. However, it is not correct for the eq1, eq2, eq3, or eq4. I do not understand why it is not correct. Please tell me the reason and how I can solve and obtain correct solution. The worksheet can be found in the File Manager Thank you for your time and help. Y-G Sung
