помогите !!!! пожалуйста ​

Answer 1

$\frac{117}{x} = \frac{13}{14} \\ x = \frac{117 \times 14}{13} = 126 \\ \\ \frac{15}{35} = \frac{x}{7} \\ x = \frac{15 \times 7}{35} = 3 \\ \\ \frac{x}{6} = \frac{40}{48} \\ x = \frac{40 \times 6}{48} = 5 \\ \\ x - 144 = 361 + 49 \\ x = 410 + 144 \\ x = 554 \\ \\ 495 - x = 129 + 246 \\ 495 - x = 375 \\ - x = 375 - 495 \\ - x = - 120 \\ x = 120$
