oblicz

1/5(10x + 2,5)- 0,4

1/3(3y-2,7)

-2/3(3,6a - 1,5b)

3(x-3)

5(y+z)

4(3x-y)

3(4a -3)

-2(7 -4n)

1/2(4z +2)

-1/3(6b-3)

0,2(x-5y)

3(1/3 a +1)

Answer 1

oblicz

1/5(10x + 2,5)- 0,4=2x+0,5-0,4=2x+0,1

1/3(3y-2,7)=y-0,9

-2/3(3,6a - 1,5b)=-2,4a+3b

3(x-3)=3x-9

5(y+z)=5y+5z

4(3x-y)=12x-4y

3(4a -3)=12a-9

-2(7 -4n)=-14+8n

1/2(4z +2)=2z+1

-1/3(6b-3)=-2b+1

0,2(x-5y)=0,2x-y

3(1/3 a +1)=a+3

Answer 2

oblicz

1/5(10x + 2,5)- 0,4=2x+0,5-0,4=2x+0,1

1/3(3y-2,7)=y-0,9

-2/3(3,6a - 1,5b)=-0,7(3,6a-1,5b)=-2,52a+1,05b

3(x-3)=3x-9

5(y+z)=5y+5z

4(3x-y)=12x-4y

3(4a -3)=12a-9

-2(7 -4n)=-14+8n

1/2(4z +2)=2z+1

-1/3(6b-3)=-2b+1

0,2(x-5y)=0,2x-y

3(1/3 a +1)=a+3
