[QUOTE="Ray Vickson, post: 4863195, member: 330118"] You have not missed anything; your answer is correct (provided that you never divide by zero anywhere, so provided that all x's a's and b's are nonzero). Your argument is very long-winded, though, and can be shortened into two lines: [tex] \frac{a_1 b_1}{x_1} = \frac{a_2 b_2}{x_2}\, ,\\ \text{so }\; \frac{x_1}{a_1 b_1} = \frac{x_2}{a_2 b_2} \, ,\\ \text{so }\; x_2 = \frac{x_1}{a_1 b_1} a_2 b_2 = \frac{a_2 b_2 x_1}{a_1 b_1} [/tex] [/QUOTE]
