Натала · Answer 1

1. (у-3) - 4 (2+у) = у-3-8-4 у = - 3 у-11

2. - 5 (1,5-3b) - 2b-16=-7,5+15b-2b-16 = - 23,5+13b

3. 6b - (2-b) - (2b+1) = 6b-2+b-2b-1==5b-3

Селивёрст · Answer 2

1. (y-3) - 4 (2+y) = y-3-8-4y=-3y-11;

3y=11;

y=11/3;

y=3,7

2. - 5 (1,5-3b) - (2b+1) = - 7,5+15b-2b-1=-8,5+13b;

13b=8,5;

b=8,5/13

b=0.65

3. 6b - (2-b) - (2b+1) = 6b-2+b-2b-1=5b-3

5b=3

b=3/5

b=0.6
