Prosze zróbcie bo mam to na jutro ; (

Answer 1

1.4(2x-4)-6= 8x - 16-6 = 8x - 22

2.3(x+2)-4(x-2)= 3x + 6 -4x + 8 = -x+14

3.-3(y-4)+3(y-6)= -3y + 12 + 3y - 18 = -6

4.6(x-y-3)-3(x+4)= 6x-6y-18 -3x - 12 =  3x-6y-30

5.x(7x-2)-4(x-2x)=  7x²-2x -4x + 8x =  7x²-2x

6.8(3a+b)-2(a-b)=24a+8b-2a+2b=22a+10b

7.9(2x+2)-6(x-4)=18x+18-6x+24=12x+42
