Proszę o pomoc !!!! Na dzisiaj ! Zadanie 1 ,2 i 3( 3 tylko abcd)

z.1 a)3b+(b+1)=3b+b+1=4b+1 b) 8n-3+(-5n+7)=8n-3-5n-7=3n-10 c) 5a-(a+1)=5a-a-1=4a-1 d) 6x-(3+5x)=6x-3-5x=x-3 e)8-3y-(-7-y+5)=8-3y-7+y-5=-4-2y f)3+(8u-5)-(5u+2)=3+8u-5-5u-2=-4+3u g) 7z-(3-4z)+(5+z)=7z-3+4z+5+z=12z+2 h) 1-5w-(w+3)-(4w-6)=1-5w-w-3-4w+6=-10w+4 zad.2 a) 5+x+(4y-5x-3)=5+x+4y-5x-3=-4x+4y+2 b) 2u-4w+(7-u+w)=2u-4w+7-u+w=u-3w+7 c)2a+(3a-2b)+(a+b)=2a+3a-2b+a+b=6a-b d) 2-3s+(2-3s+4t)+(1+6s)=2-3s+2-3s+4t+1+6s=4t+5 e) 5m+3n-5-(2m-3n-5)=5m+3n-5-2m+3n+5=3m+6n f)3-(4a-6b)+(2-a-7b)=3-4a+6b+2-a-7b=-5a-b+5 g)-2c+4-(3c+2d)-(5d-2)=-2c+4-3c-2d-5d+2=-5c-7d+6 h) 8p-(3-4p-r)-(2+3p+5r)=8p-3+4p+r-2-3p-5r=9p-4r-5 zad.3  a) 2a+(4a-3b+5c)+(5c-2b)=2a+4a-3b+5c+5c-2b=6a-5b+10c b)5x+3y+(2y-4z)-(5y+6z)=5x+3y+2y-4z-5y-6z=5x-10z c)-3r-(2r-4s-t)-(6r+5s)=-3r-2r+4s+t-6r-5s=-11r-s+t d)4k-(2m+n)-(-k-m)+(3m-n)=4k-2m-n-k+m+3m-n=3k+2m-2n LICZĘ NA NAJ ;)
