Решите уравнение. 1) 1/3х + 1/4х - 1/5х = 2) 1(8/9)х + 2(2/15) = 3) 2(1/3) - 1/24х = 4) 6(1/6)х - 11/18 =

1) 1/3х + 1/4х - 1/5х = 1(8/15);20/60х + 15/60х - 12/60х = 1(8/15);23/60х = 23/15;х = 23/15 : 23/60;х = 23/15 * 60/23;х = 4.

2) 1(8/9)х + 2(2/15) = 4(29/30);1(8/9) = 4(29/30) - 2(2/15);1(8/9)х = 2(5/6);х = 2(5/6) : 1(8/9);х = 17/6 * 9/17;х = 1(1/2).

3) 2(1/3) - 1/24х = 13/16;1/24х = 2(1/3) - 13/16;1/24х = 1(25/48);х = 1(25/48) : 1/24;х = 73/48 : 24/1;х = 36(1/2).

4) 6(1/6)х - 11/18 = 5/12;6(1/6)х = 5/12 + 11/18;6(1/6)х = 5/12 + 11/18;6(1/6)х = 37/36;х = 37/36 : 6(1/6);х = 37/36 * 6/37;х = 1/6.
