ZAd 1
2x1/2=1
-5x1/5= -1
11/2:3= 2:11=0.18:3=0.06
3/8x9-3/8=3/8=0.375x9-0.375=3.375-0.375=3
5x3=15
tamtych to już nie umiem

a)2x(+3)=6
B)5x(3-1)=10
c) nie umiem
d) nie umiem
f) nie umiem
g) -3(3-2)=-3
h nie umiem
zad 3
6x-2:(-2)=6
6x-2x 1\3=6x(-2)x0.33=-3.96
6x-2:3=-4
6x-2x3=-36
Myślę ze pomogłam trudne strasznie było
2x* 1/2 = 2/2x = x
-5y*1/5= -5/5y = -y
1 i 1/2 z : 3 = 3/2 z * 1/3 = 3/6 z = 1/2z
3/8w *9-3/8 = 27/8w - 3/8
5x * 3 = 15x
9y * 1/9 = y
-6z *(-1/6) = z
2/3u * 3/2 = u
-1/2v :(- 4 )= -1/2v*(-1/4) = 1/8 v
Zad.2
a)2(x+3) = 2x + 6
b) 5(3x-1) =15 x -5
c) - 4(2a - b) = -8a + 4b
d) -2(-4b+3) = 8b -6
e)(a+b)*(-4)= -4a-4b
f)(4-5x+6y)*3= 12-15x+18y
g)-3(3x -2) = -9x +6
h)-1(3x-y+2) = -3x+y -2
Zad.3
a) ( 10x+ 2y) : 2 = 5x + y
b)(3a +12) :(-3) = -a-4
c) (24a-4b): 8 = 3a -0,5b
d) 4u-6v) : 1/2 8/1u - 12/1= 8u -12v
Zad.4
6x-2:(-2) =6x +1
6x-2*1/3 = 6x -2/3
6x-2:3 = 6x -2/3
6x - 2 * 3 = 6x - 6
