Answer 2

$\frac{3x + 10}{5x - 8} = \frac{11}{6} \\ \\ 3x + 10 = \frac{11}{6}(5x - 8) \\ \\ 3x + 10 = \frac{11(5x - 8)}{6} \\ \\ 18x + 60 = 11(5x - 8) \\ \\ 18x + 60 = 55x - 88 \\ \\ 60 = 55x - 88 - 18x \\ \\ 60 = 37x - 88 \\ \\ 60 + 88 = 37x \\ \\ 148 = 37x \\ \\ \frac{148}{37} = x \\ \\ 4 = x \\ \\ x = 4$
