First, we need to simplify both sides of the equation:

5/8 × (4/5x - 1.6) + 0.75 × (1/3x + 1 1/3) = 5 - 3x
(5/8) × (4/5x) - (5/8) × 1.6 + (0.75) × (1/3x) + (0.75) × 1 1/3 = 5 - 3x
(1/2)x - 1 + (1/4)x + 1 = 5 - 3x
(1/2 + 1/4)x = 5 - 3x
(3/4)x = 5 - 3x
3x/4 + 3x = 5
3x + 12x = 20
15x = 20
x = 20/15
x = 4/3

Therefore, the solution to the equation is x = 4/3.
