1. 6x-2*3=... 6x - 6
2. 6x-2:3=... 6x - 2/3
3. 6x-2+3=... 6x + 1
4. 6x-2-3=...6x - 5

Ps. w 3 zadaniu o to chodziło? :)
5(3x-1)= 15 x - 5
(-4)*(2a-b)= (-8)a + 4b
-2(-4b+3)= 8b - 6
(a+b)*(-4)= (-4)a - 4b
(4-5x+6y)*3= 12 - 15x + 18y
zadanie 2
(6x -2y) : 2= 3x - y
(-3a-1 1/2):(-3)= a plus 1\2
(2,4a-1,6b):0,8= 3a - 2b
(4u-6v):(-1/2) = -8u plus 12v
zadanie 3
1. 6x-2*3= 6x - 6
2. 6x-2:3= 6x - 2/3
3. 6x-2+3= 6x + 1
4. 6x-2-3=6x - 5
5. 6x-2*1/3=6x - 2/3
6. 6x-2:1/2=6x - 4
7. 6x-2-2=6x - 4
8. 6x-2+2= 6x
9. 6x-2*2=6x - 4
10. 6x-2:(-2)= 6x + 1
