Раскройте скобки и подобные слогаемые (782, 5,3b-(2b+3). 9,6b+(7-0,4b). (y-4)*2+10y : (2у+5)*4-11у: 2с-(9-5,1с): -5с+(13-6с): 4х+2(0,5х+3): 6х-3(х-7)

1) = 782783/1000=782 783/1000=782,783
2) = 53/10*b-(2b+3)=5 3/10b-(2b+3)=3 3/10b-3
3) = 96/10*b+(7-4/10*b)=9 6/10b-(2/5b-7)=9 1/5b+7
4) = y*2+ -4*2+10y=2y-8+10y=12y-8
5) = 2y*4+5*4-11y=8y+20-11y= -3y+20
6) = 2c-(9-51/10*c)=2c+(5 1/10c-9)=7 1/10c-9
7) = -5c-(6c-13)= -11c+13
8) = 4x+2*(5/10*x+3)=4x+2*(1/2x+3)=4x+(2*1/2x+2*3)=4x+(x+6)=5x+6
9) = 6x-(3*x+3* -7)=6x-(3x-21)=3x+21
