╔════════════════════════╗

 \sf ➜ \: \frac{x-1}{x} + \frac{x}{x-1} = \frac{61}{30}

 \sf ➜ \: \frac{(x-1)(x-1) + (x × x)}{x(x-1)} = \frac{61}{30}

 \sf ➜ \: \frac{x(x-1) -1(x-1) + x²}{x²-x} = \frac{61}{30}

 \sf ➜ \: \frac{x²-x -x+1 + x²}{x²-x} = \frac{61}{30}

 \sf ➜ \: \frac{2x²-2x+1}{x²-x} = \frac{61}{30}

 \sf ➜ \: (2x²-2x+1)30 = 61(x²-x)

 \sf ➜ \: 60x²- 60x + 30 = 61x² - 61x

 \sf ➜ \: 60x²- 60x + 30 - 61x² + 61x = 0

 \sf ➜ \: -x² + x + 30 = 0

 \sf ➜ \: -x² + x + 30 = 0

 \sf ➜ \: -x² + 6x - 5x + 30 = 0

 \sf ➜ \: -x(x - 6) - 5(x - 6) = 0

 \sf ➜ \: (-x - 5)(x - 6) = 0

___________________________

 \sf -x -5 = 0

 \sf -x = 5

 \boxed{\sf x = -5}

___________________________

 \sf x -6 = 0

 \boxed{\sf x = 6}

___________________________

 \sf \red{Therefore, \: value \: of \: x \: is \: 6 \: or \: -5}
