Question

3(2-a)-4(a+3)=14x-4(3x-3,5)=11,2-1,2(10-5x) =2(6+7x)-(12x+11)=8x-(19x-6)+4(3x-1)=-5(2x-1)-3(3-5x) =

Answer 1

1) 3(2-a)-4(a+3)=6-3а-4а-12=-7а-6
2)14x-4(3x-3,5)=14х-12х+12=2х+12
3)11,2-1,2(10-5x) =11,2-12+6х=6х-0.8
4)2(6+7x)-(12x+11)=12+14х-12х-11=2х+1
5)8x-(19x-6)+4(3x-1)=8х-19х+6+12х-4=х+2
6)-5(2x-1)-3(3-5x) =-10х+5-9+15х=5х-4
