1) 0,3x + 1,6x - 0,5x = 1,9x - 0,5x = 1,4x

2) 9,25y - 2,3y + 7,05y = 6,95y + 7,05y = 14y

3) 3,46x + 9,17x - 2,63x = 12,63x - 2,63x = 10x

4) 4,82y - 1,9y + 3,08y = 2,92y + 3,08y = 6y

Verified answer

Ответ:

1) 1,4·x

2) 14·y

3) 10·x

4) 6·y

Пошаговое объяснение:

1) 0,3·x + 1,6·x - 0,5·x  = (0,3 + 1,6 - 0,5)·x=(1,9 - 0,5)·x=1,4·x

2) 9,25·y - 2,3·y + 7,05·y  = (9,25 - 2,3 + 7,05)·y =

= (9,25 + 7,05 - 2,3)·y = (16,3 - 2,3)·y = 14·y

3) 3,46·x + 9,17·x - 2,63·x  = (3,46 + 9,17 - 2,63)·x  = (12,63 - 2,63)·x  = 10·x

4) 4,82·y - 1,9·y + 3,08·y = (4,82 - 1,9 + 3,08)·y =

= (4,82 + 3,08 - 1,9)·y = (7,9 - 1,9)·y = 6·y
