Answer 2

Answer:

$\frac{3x - 4}{7} + \frac{7}{3x - 4} = \frac{5}{2} \\ let \: \frac{3x - 4}{7} = y \: \: \: \frac{7}{3x - 4} = \frac{1}{y} \\ y + \frac{1}{y} = \frac{5}{2} \\ \frac{{y}^{2} + y}{y} = \frac{5}{2} \\ 2 {y}^{2} + 2y = 5y \\ 2 {y}^{2} + 2y - 5y = 0 \\ 2 {y}^{2} - 3y = 0 \\ y(2y - 3) = 0 \\ y = 0 \\ 2y - 3 = 0 \\ 2y = 3 \\ y = \frac{3}{2} \\ \frac{3x - 4}{7} = \frac{3}{2} \\ 6x - 8 = 21 \\ 6x = 21 + 8 \\ 6x = 29 \\ x = \frac{29}{6} \\ y = 0 \\ \frac{3x - 4}{7} = 0 \\ 3x - 4 = 0 \\ 3x = 4 \\ x =\frac{4}{3}$
