Answer 1

a) 7 ·(a+4-5c)-2 ·(9-3a+c)-13a-10=

7a+28-35c-18+6a-2c-13a-10=-37c

b) 2p-4r-5s+(28r-14p+35s):7+18=

2p-4r-5s+4r-2p+5s+18=18

c) (6a-2b+1) ·(-1)+2 ·(b-3a+)=

-6a+2b-1+2b-6a=4b-1

d)  ·(x-5y+4w)+3 ·(x-jedna szósta y+w)=

x-5y+4w+3x-3/6y+3w=4x-5 3/6y+7w=4x-5 1/2y+7w

Answer 2

a)7 ·(a+4-5c)-2 ·(9-3a+c)-13a-10=7a+28-35c-18+6a-2c-13a=10-37c

b) 2p-4r-5s+(28r-14p+35s):7+18=2p-4r-5s+4r-2p+7s+18=2s+18

c)(6a-2b+1) ·(-1)+2 ·(b-3a+)=-6a+2b-1+2b-6a=4b-1

d)(x-5y+4w)+3 ·(x-jedna szósta y+w)=x-5y+4w+jedna druga y+ 3w=x-4,5y+7w
