Ответ:
а)(2х-у)-(4у+2х)-(6х-у)=2х-у-4у-2х-6х+у=2х-2х-6х-у-4у+у= -6х-4у
б) 0,5(2m+n)-2(0,5m-3n)=m+0,5n-m+6n=m-m+0,5n+6n=6,5n
в)[tex]-\frac{2}{3} (6a-3b)+\frac{1}{5} (10b-5a)= -2*2a+2b+2b-a= -4a+2b+2b-a= -4a-a+2b+2b= -5a+4b[/tex]
г)6х(3у-4)-(15ху-24х)-5ху=18ху-24х-15ху+24х-5ху
= 18ху-15ху-5ху-24х+24х= -2ху
a) (2x-y)-(4y+2x)-(6x-y)=2x-y-4y-2x-6x+y=-6x-4y
б) 0,5(2m+n)-2(0,5m-3n)=m+0,5n-m+6n=6,5n
в) -2/3(6a-3b)+1/5(10b-5a)=-4a+2b+2b-a=4b-5a
г) 6x(3y-4)-(15xy-24x)-5xy=18xy-24x-15xy+24x-5xy=-2xy
