Answer 1

-2a+b-a-2b+3a=-b

-ab+b do kwadratu+3ab-2ab=b do kwadratu

2/3x+1/3y+2 i 1/3x-1/3y=2xi3/3x=3x

15xy-4x+8y-6xy+5x-xy=x+8y+8xy

0,2xdokwadratu-2y+1,8xdokwadratu+4,3y6-x=2x do kwadratu-x-2y+4,3y6

-1/4m+1/8n-1/8m+0,375m=1/8n-1/4m-1/8m+0,375m=(1,8n-0,25-0,125+0,375)=1,8n+374,625

2 i 1/2+3x-4-2x=x-2,5

2a+3b-4a+7b=-2a+10b

2a+3-4a+7b=-2a+7b+3

4a-2-8a-5=-4a-7
