What's one and a half plus two and a half plus three and a half plus four and a half

The sum of the integral part is 10, the sum of the fractional part is 2, and the result is 12

The equation is formulated according to the following conditions: (1) four fifths of the sum of Y and - 2 is equal to three times of it
(2) 40% of a number x is one third less than one third of its opposite

(1) four fifths of the sum of Y and - 2 is equal to three times of it
[y + (- 2)] × 4 / 5 = 3Y
(2) 40% of a number x is one third less than one third of its opposite
40%x=(-x)×1/3-1/3
