Пошаговое объяснение:

1/3(3,75 - x) = 1/2(x - 2,5)

1/3(3. 75/100 - x) = 1/2(x - 2. 5/10)

1/3(3. 3/4 - x) = 1/2(x - 2. 1/2)

1/3(15/4 - x) = 1/2(x - 5/2)

15/12 - 1/3x = 1/2x - 5/4

5/4 - 1/3x = 1/2x - 5/4

-1/3x - 1/2x = -5/4 - 5/4

-2/6x - 3/6x = -10/4

-5/6x = -10/4

x = -10/4 : (-5/6)

x = -10/4 * (-6/5)

x = 60/20

x = 3
