The solution equation is as follows: {2x / 3 + 3Y / 4, 4x / 5 + 5Y / 6 = 7 / 15
(2 / 3) x + (3 / 4) y = 1 / 2 (1) X12 to get 8x + 9y = 6 (3) (4 / 5) x + (5 / 6) y = 7 / 15 (2) x30 to get 24x25y = 14 (4) to (3) X3 to get 24x + 27y = 18 (5) to (4) - (5) to get - 2Y = - 4, that is, y = 2 to substitute y = 2 into (3) to calculate x = - (3 / 2)
