Step-by-step explanation:
x/(2x - 4) - (2x - 11)/(x + 2) = 5/8
x/(x - 2) - (4x - 22)/(x + 2) = 5/4
x(x + 2) - (4x - 22)(x - 2) = 5/4(x + 2)(x - 2)
4(x² + 2x - 4x² + 8x + 22x - 44) = 5(x² - 4)
4(-3x² + 32x - 44) = 5x² - 20
- 12x² + 128x - 176 - 5x² + 20 = 0
- 17x² + 128x - 156 = 0
17x² - 128x + 156 = 0
x = (64 ± 38)/17
x = 6
or
x = 26/17
