wykonaj odejmowanie 17a-(2b-3a)= 3,5a-(12a-4,5+b)= 25x-(4x+18y-9)= (32x-22y+45)-6x= (3a-2)-(24a-7)= (24x-y+35)-(6x-12)= -(27a-31)-(5a+2)-19= (54x-30)-(11x-25)-(22x-9)= wykonAJ dodawanie (5a-125)+(4a-21)+(36-33a)= (3x-7)+(35x-39)+(2x-7)= prosze nie piszcie samych wyników tylko też obliczenia :D

Answer 1

Odejmowanie: 

17a-(2b-3a)=17a-2b+3a=20a-2b

3,5a-(12a-4,5+b)=3,5a-12a+4,5-b=-8,5a-b+4,5

 

25x-(4x+18y-9)= 25x-4x-18y+9=21x-18y+9

 

(32x-22y+45)-6x= 32x-22y+45-6x=26x-22y+45

 

(3a-2)-(24a-7)=3a-2-24a+7=-21a+5

 

(24x-y+35)-(6x-12)=24x-y+35-6x+12=18x-y+47

 

-(27a-31)-(5a+2)-19= -27a+31-5a-2-19=-32a+10 

 

(54x-30)-(11x-25)-(22x-9)= 54x-30-11x+25-22x+9=21x+4 

 

Dodawanie: 

(5a-125)+(4a-21)+(36-33a)=5a-125+4a-21+36-33a=-24a-113

 

(3x-7)+(35x-39)+(2x-7)=3x-7+35x-39+2x-7=40x-53

 

Mam nadzieję, że pomogłam, więc liczę na naj :) 

Answer 2

 

Odejmowanie 

17a-(2b-3a)=17a-2b+3a=20a-2b

3,5a-(12a-4,5+b)=3,5a-12a+4,5-b=-8,5a-b+4,5

 

25x-(4x+18y-9)= 25x-4x-18y+9=21x-18y+9

 

(32x-22y+45)-6x= 32x-22y+45-6x=26x-22y+45

 

(3a-2)-(24a-7)=3a-2-24a+7=-21a+5

 

(24x-y+35)-(6x-12)=24x-y+35-6x+12=18x-y+47

 

-(27a-31)-(5a+2)-19= -27a+31-5a-2-19=-32a+10 

 

(54x-30)-(11x-25)-(22x-9)= 54x-30-11x+25-22x+9=21x+4 

 

Dodawanie

(5a-125)+(4a-21)+(36-33a)=5a-125+4a-21+36-33a=-24a-113

 

(3x-7)+(35x-39)+(2x-7)=3x-7+35x-39+2x-7=40x-53
