Question

Решите уравнение x-/6=1/9;x+5/24=7/12;x-1/6=7/9;y+2/5=1/2

Answer 1

х - 1/6 = 1/9
х = 1/9 + 1/6 
х = 2/18 + 3/18
х = 5/18

х +5/24 = 7/12
х = 7/12 - 5/24
х = 14/24 - 5/24
х = 9/24 = 3/8

х - 1/6 = 7/9
х = 1/6 + 7/9
х = 3/18 + 14/18
х = 17/18

у + 2/5 = 1/2
у = 1/2 - 2/5
у = 5/10 - 4/10
у = 1/10
