Question

potrzebuje na teraz!!!!!!!! daje naj
doprowadz do najprostrzej postaci
2(3a-b)+4a+2b :2 =
5(-4x-2y)-8x-10y :2=
10(0,3+0,4b)-5(-a+4b=
8a+16b: -8 - 4a-5b: 1/2

Answer 1

2(3a-b)+4a+2b :2 =6a-2b+4a+b= 10a -b
5(-4x-2y)-8x-10y :2=-20x-10y - 8x -5y= - 28x -15y
10(0,3+0,4b)-5(-a+4b=3 + 4b +5a -20b= 5a -18b + 3
8a+16b:( -8 )- 4a-5b: 1/2 = 8a - 2b - a - 10b= 7a - 12 b

Answer 2

2(3a-b)+4a+2b:2=6a-2b+4a+b=10a-b

5(-4x-2y)-8x-10y:2=-20x-10y-8x-5y=12x-15y

10(0,3+0,4b)-5(-a+4b)=3+4b+5a-20b=3+5a-16b

8a+16b:-8-4a-5b:1/2=8a-2b-4a-10b=4a-12b
