Решите уравнение: 1)х+1/8х=3/4 2) 2у-2/5у=6 2/5 3) 3/5х-1/3х=6 1/4 4) (2х-1/8х) : 1/2=1/3

1) х + 1/8х = 3/4 1 1/8х = 3/4 х = 3/4 : 1 1/8 = 3/4 : 9/8 = 3/4 * 8/9 = 2/3 2) 2у - 2/5у = 6 2/5 1 3/5у = 6 2/5 у = 6 2/5 : 1 3/5 = 32/5 : 8/5 = 32/5 * 5/8 = 4 3) 3/5х - 1/3х = 6 1/4 (9-5)/15х = 6 1/4 4/15х = 6 1/4 х = 6 1/4 : 4/15 = 25/4 * 15/4 = 375/16 = 23 7/16 4) (2х - 1/8х) : 1/2 = 1/3 1 7/8х = 1/3 * 1/2 = 1/6 х = 1/6 : 1 7/8 = 1/6 : 15/8 = 1/6 * 8/15 = 4/45
