nakayori Пусть x - двухколесные мотоциклы ИЖ
y - трехколесные мотоциклы Урал
z - четырехколесные мотоколяски для инвалидов

Тогда всего колес 2x+3y+4z

Составим систему уравнений с учетом условия задачи
{1. x+y=10 (тк всего мотоциклов 10)
{2. z-x = 5 (тк колясок на 5 больше ИЖ)
{3. 2x+3y+4z = 62 (всего колес)

Решаем систему, выразив буквы из первых двух уравнений и подставив их значения в третье
{1.y=10-x
{2.z=5+x
{3. 2x+3(10-x)+4(5+x)=62

Решим отедьлно третье уравнение
2x+30-3x+20+4x=62
3x=62-30-20
3x=12
x=4

Подставим икс в первые два уравнения, найдем
y=10-4=6
z=5+4=9

Ответ:4 - двухколесные мотоциклы ИЖ
6 - трехколесные мотоциклы Урал
9- четырехколесные мотоколяски для инвалидов
