2 число - 3х - 24
3х+3х-24=0
6х= 24
х=24 : 6
х=4
1 число = 3х = 4*3= 12
2 число = 3х - 24 =3*4-24=12-24= -12

Обозначим Х1 -первое число, Х2 -второе. По условию задачи можем записать Х1=3*Х2, которое далее подставляем
1) запишем как сказано: Х1-24=Х2 - первое уменьшили на 24 и получили второе.
Подставляем Х1: 3*Х2-24=Х3, приводим подобные 3*Х2-Х2=24 Х2(3-1)= 24 Х2=12
Х1=3*Х2=36
2) Х1-18=Х2 3*Х2-18=Х2 ... Х2*2=18 Х2=9 Х1=27
3) Х1-10=Х2+6 ... Х2=8 Х1=24
