Answer:

$1). \: \frac{9x - 1}{4} - \frac{4x + 6}{3} = \frac{5x}{2} - 2 \\ \\ \frac{27x - 3 - 16x - 24}{12} = \frac{5x - 4}{4} \\ 11x - 27 = 3(5x - 4) \\ 11x - 27 = 15x - 12 \\ 11x - 15x = 27 - 12 \\ - 4x = 15 \\ \boxed{x = \frac{ - 15}{4} } \\ \\ 2). \: \frac{6x - 3}{8} = \frac{8x + 1}{1} \\ \\ 6x - 3 = 8(8x + 1) \\ 6x - 3 = 64x + 8 \\ 6x - 64x = 8 + 3 \\ - 58x = 11 \\ \boxed{ x = \frac{ - 11}{58} } \\ \\ 3). \: \frac{5t - 3}{4} - \frac{3t + 4}{12} = \frac{10}{15} - t \\ \\ \frac{15t - 9 - 3t - 4}{12} = \frac{10 - 15t}{15} \\ 5(12t - 13) = 4(10 - 15t) \\ 60t - 65 = 40 - 60t \\ 120t = 105 \\ \boxed{t = \frac{7}{8} } \\ \\ 4). \: \frac{4x + 2}{3} = \frac{3}{5} \\ \\ 5(4x + 2) = 3 \times 3 \\ 20x + 10 = 9 \\ \boxed{x = \frac{ - 1}{20} } \\ \\ 5). \: \frac{y + 4}{5} - \frac{y - 7}{3} + \frac{2y - 2}{12} = 9 \\ \\ \frac{12y + 48 - 20y + 140 + 10y - 10 }{60} = 9 \\ 2y + 178= 540 \\ 2y = 362 \\ \boxed{y = 181} \\ \\ 6). \: \frac{7x}{2} + \frac{x}{4} - \frac{x}{8} = 11 \\ \\ \frac{28x + 2x - x}{8} = 11 \\ 29x = 88 \\ \boxed{x = \frac{88}{29} } \\ \\\red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$
