пусть вместимость автоцистерны - х, тогда жел.дор.цистерна вмещает - 5х, разница между ними - 5х-х или 48 т, отсюда

1) 5х-х=48

    4х=48

    х=48:4

    х=12 тонн - вмещает автоцистерна

2) 12*5=60 ИЛИ 12+48=60 тонн - вместимость жел.дор. цистерны.

допустим, автоцистерна вмещает х т, тогда

5х=х+48

5х-х=48

4х=48

х=48/4

х=12т автоцистерна вмещает

12+48=60т железнодорожная цистерна   или 5*12=60т
