Решите уравнение. 1) -1/3х - 1/4х + 1/5х = 1(3/15) 2) 2(5/6)х - 3(3/4)х - 1(5/12)х = -1(5/9)

1) -1/3х - 1/4х + 1/5х = 1(3/15);-20/60х - 15/60х + 12/60х = 23/15³;-23/60х = 23/15;х = 23/15 : (-23/60);х = -4.

2) 2(5/6)х - 3(3/4)х - 1(5/12)х = -1(5/9);2(10/12)х - 3(9/12)х - 1(5/12)х = -1(5/9);-2(1/3)х = -1(5/9);х = (-1(5/9)) : (-2(1/3));х = 2/3.
