Đổi 80 km =8 000 000 cm

Trên bản đồ tỉ lệ xích 1:2 000 000 , khoảng cách đó là:

         8 000 000: 2 000 000= 4 (cm)

ta có: \(\frac{3}{4}x-\frac{5}{6}=\frac{7}{8}\)<=> \(\frac{3}{4}x=\frac{41}{24}\)

                                => \(x=\frac{41}{18}\)

Vậy x= \(\frac{41}{18}\)

ta có: \(\frac{7}{6}-\frac{5}{2}x=\frac{13}{9}+\frac{7}{4}x\)

<=> \(\frac{7}{6}-\frac{13}{9}=\frac{7}{4}x+\frac{5}{2}x\)

<=> \(-\frac{5}{18}=\frac{17}{4}x\)

=> \(x=-\frac{10}{153}\)
