26. Determine pelo menos três soluções distin- tas para cada uma das seguintes equações: \( \begin{array}{ll}\text { a) } 5 x-3 y=5 & \text { c) } 2 x+y=20 \\ \text { b) } \frac{x}{2}+\frac{y}{4}=\frac{7}{8} & \text { d) } 2 x-4 y=12\end{array} \)

Two cars started their journey at the same time, one started from the Aztec stadium and the other from six flags Mexico. The red car started its journey with a speed of \( 150 \mathrm{~m} / \mathrm{s} \) and the other blue car started its journey with a speed of \( 120 \mathrm{~m} / \mathrm{s} \). We want to know the meeting time of the cars that started their journey and the distance that each of them travels if they were 20,000 metres apart from each other.
