димасик138 · Answer

Х = 2/3х + 1х - 2/3х = 11/3х = 1х = 1 : 1/3х = 3х - 1/2 = 3/4хх - 3/4х = 1/21/4х = 1/2х = 1/2 : 1/4х = 2х - 2/3 = 5/6х х - 5/6х = 2/31/6х = 2/3х = 2/3 : 1/6х = 41 4/5у = у + 41 4/5у - у = 44/5у = 4у = 4 : 4/5у = 52/3у - 1/3 = 5/9у2/3у - 5/9у = 1/31/9у = 1/3у = 1/3 : 1/9у = 33/4у - 2/3 = 7/12у3/4у - 7/12у = 2/31/6у = 2/3у = 2/3 : 1/6у = 4...
