Решить уровнение (4 1/6+11 1/4)4/15=2/3х+ 5 2/3

15 5/12 * 4/15 = 2/3x + 5 2/3
4 1/9 = 2/3x + 5 2/3
2/3x = 4 1/9 - 5 2/3
2/3x = -1 5/9
x = -1 5/9 : 2/3
x = -2 1/3

(4 1/6 + 11 1/4) *  4/15 = 2/3х + 5 2/3,
(25/6 + 45/4) * 4/15 = 2/3х + 5 2/3,
(50/12 + 135/12) * 4/15 = 2/3х + 5 2/3,
185/12  * 4/15 = 2/3х + 5 2/3,
37/9 = 2/3х + 5 2/3,
2/3х = 37/9 - 5 2/3,
2/3х = 37/9 - 17/3,
2/3х = 37/9 - 51/9,
2/3х = -14/9,
х = -14/9 : 2/3,
х = -14/9 * 3/2,
х = - 7/3,
х = - 2 1/3
