If positive numbers a and B satisfy 2A + 3B = 6, then the minimum value of 2 / A + 3 / B is

If positive numbers a and B satisfy 2A + 3B = 6, then the minimum value of 2 / A + 3 / B is

It should be like this
(2a+3b)(2/a+3/b)
=4+6a/b+6b/a+9
=13+6(a/b+b/a)
Because a > 0, b > 0
So a / B + B / a ≥ 2 if and only if a / b = B / A, i.e. a = B, the equal sign holds
Because 2A + 3B = 6
So when a = b = 1.2, (2a + 3b) (2 / A + 3 / b) has a minimum value of 13 + 6 * 2 = 25
So when a = b = 1.2, 2 / A + 3 / B has a minimum value of 25 / (2a + 3b) = 25 / 6
