Помогите плиз!!? 2(3x-6), -10-2(2x-7), -2(4+3x)+8x,. 28x-5(6x-0,2),. 4x+(8-6x), -13x-(4-9x), 2(6+7x)-(12x+11),. 8x-(19x-6)+4(3x-1), -5(2x-1)-3(3-5x)

Answer 1

1)2(3х-6)=6х-12

2)-10-2(2х-7)=-10-4х+14=4-4х

3)-2(4+3х)+8х=-8-6х+8х=-8+2х

4)28х-5(6х-0,2)=28х-30х+1=-2х+1

5)4х+(8-6х)=4х+8-6х=-2х+8

6)-13х-(4-9х)=-13х-4+9х=-4х-4

7)2(6+7х)-(12х+11)=12+14х-12х-11=1+2х

8)8х-(19х-6)+4(3х-1)=8х-19х+6+12х-4=

х+2

9)-5(2х-1)-3(3-5х)=-10х+5-9+15х=5х-4
