Przekształc wyrażenia algebraiczne do najprostszej postaci:)
a)5(x-y)+2(4x+2y)-3(2x+y)=
b)5(x+2y-3z)-2(4x-3y+z)=
c)-(k-m-n)+2(k+2m+3n)-kmn=
d)2p(3p-2r)+3r(p-2r)=
prosze żeby było dobrze
2.Doprowadz do najprostszej postaci
a)3(a+2b-3c)+7(2a-4b+5c)-5(-3a-4b-5c)=
b)-4(-2x+6y+5z)-8(9x+8y-7z)+5(3x+6y+9z)=
c)2/3(dwie trzecie)(3a+6b-12c)+3/5(Trzy piąte(10a-15b+20c)-0,5(16a+24b-36c)=
prosze napiszcie

a)5(x-y)+2(4x+2y)-3(2x+y)=5x-5y+8x+4y-6x-3y=7x-4y
b)5(x+2y-3z)-2(4x-3y+z)=5x+10y-15z-8x+6y-2z= -3x+16y-17z
c)-(k-m-n)+2(k+2m+3n)-kmn= -k+m+n+2k+4m+6n-kmn=1k+5m+7n-kmn
d)2p(3p-2r)+3r(p-2r)=6p²-4pr+3pr-6r²= -pr+6p²-6r²

a)3(a+2b-3c)+7(2a-4b+5c)-5(-3a-4b-5c)=3a+6b-9c+14a-28b+35c+15a+20b+25c= 32a-2b+51c
b)-4(-2x+6y+5z)-8(9x+8y-7z)+5(3x+6y+9z)=8x-24y-20z-72x-64y+56z+15x+30y+45z=
-49x-58y+81z
c)⅔(3a+6b-12c)+⅗(10a-15b+20c)-₀/₅(16a+24b-36c)=2a+4b-8c+6a-9b+12c-8a-12b+18c=
-17b+22c
