(i) \(x + y + z = 5\); \(2x - y + z = 9\); \(x - 2y + 3z = 16\)
Answer:
\(x =\)
\(y =\)
\(z =\)
(ii) \(\frac{1}{x} - \frac{2}{y} + 4 = 0\); \(\frac{1}{y} - \frac{1}{z} + 1 = 0\); \(\frac{2}{x} + \frac{3}{x} = 14\)
Answer:
\(x =\)
\(y =\)
\(z =\)
(iii) \(x + 20 = \frac{3y}{2} + 10 = 2z + 5 = 110 - (y + z)\)
Answer:
\(x =\)
\(y =\)
\(z =\)
