Answer 2

Zadanie 61

a) 6a+(2a+1)-(a+5)=6a+2a+1-a+5=8a+1-a+5=7a+6

b)2x-(3x-1)+(x-3)=2x-3x-1+x-3=-1x-1+x-3=-1+3=2

c)-7k-(k+2)-(-k-3)=-7k-k+2+k-3=-6k+2+k-3=-5k+(-1)

 

Zadanie 62

a)3x+(2x+3y+1)=3x+2x+3y+1=5x+3y+1

b)4a-(5b-4a+2)=4a-5b-4a+2=-5b+2

c)2m+(-3k-2m-3)=2m+(-3k)-2m-3=-3k-3

d)-5s+(6s-4p-8)=-5s+6s-4p-8=1s-4p-8

e)-3d-(-c+5d-7)=-3d+c+5d-7=3d-7

 

Zadanie 63

a)2a-(3a+4+B )=2a-3a+4+b=-a+4+b
b)3k+(4q-5k+7)=3k+4q-5k+7=-2k+4q+7
c)6z-(-2j+8-z)=6z+2j+8-z=5z+2j+8
d)-x+(9y-6x-1)=-x+9y-6x-1=-7x+9y-1
e)-7e-(-w+4e-2)=-7e+w+4e-2=-3e+w-2
