2:3=
8*2/3=
20-(-5)=
2. rozwiąż równania :
1/7x = -2
-1/6u=1/3
5a=0
5y=13
y*12= -60
-7b=7/8
-3/4z=3/4
-2w= -1/2
22(-c)= -66
lets go prosze :)

Answer 1

-6*(-1)= 6
2:3= 0,66666667
8*2/3= 16 / 3 = 5całych i 1/3
20-(-5)= 20+5 = 25
2. rozwiąż równania :
1/7x = -2
x = -2 * 7 = -14
-----------------------------------
-1/6u=1/3
u = 1/3* (-6)
u = -2
-------------------------------
5a=0
a = 0
----------------------------
5y=13
y = 13/5
y = 2 całe i 3/5
-----------------------------
y*12= -60
y = -60 / 12
y = -5
--------------------------------
-7b=7/8
b = 7/8 * (-1/7)
b= - 1/8
----------------------------
-3/4z=3/4
z = 3/4 * 4/3
z= 1
--------------------------
-2w= -1/2
w= -1/2 * (-1/2)
w = 1/4
--------------------------
22(-c)= -66
-c = -66 / 22
-c = -3
c = 3

Answer 2

1.Uzupelnij
-6*(-1)= 6
2:3=0,66666666
8*2/3=16/3=5i1/3
20-(-5)=20+5=25
2. rozwiąż równania :
1/7x = -2/:1/7
x=-2*7
x=-14

-1/6u=1/3 /: -1/6
u=-2

5a=0/:5
a=0

5y=13/:5
y=2i 3/5

y*12= -60/:12
y=-5

-7b=7/8 /*8
-56b=7/:-56
b=-1/8

-3/4z=3/4 /*4
-3z=3/:-3
z=-1


-2w= -1/2 /*2
-4w=-1 /: -4
w=1/4

22(-c)= -66/:22
-c=-3/*-1
c=3
