[6.4] En los ejercicios 61-70 resuelve cada ecuación. \( \begin{array}{llll}\text { 61. } \frac{3}{4}=\frac{12}{x} & \text { 62. } \frac{x}{1.5}=\frac{x-4}{4.5} & \text { 63. } \frac{3 x+4}{5}=\frac{2 x-8}{3} & \text { 64. } \frac{x}{4.8}+\frac{x}{2}=1.7 \\ \text { 65. } \frac{2}{y}+\frac{1}{5}=\frac{3}{y} & \text { 66. } \frac{2}{x+4}-\frac{3}{x-4}=\frac{-11}{x^{2}-16} & \text { 67. } \frac{x}{x^{2}-9}+\frac{2}{x+3}=\frac{4}{x-3} \\ \text { 68. } \frac{7}{x^{2}-5}+\frac{3}{x+5}=\frac{4}{x-5} & \text { 69. } \frac{x-3}{x-2}+\frac{x+1}{x+3}=\frac{2 x^{2}+x+1}{x^{2}+x-6} & \text { 70. } \frac{x+1}{x+3}+\frac{x+2}{x-4}=\frac{2 x^{2}-18}{x^{2}-x-12}\end{array} \)
