Question

Реши уравнения:

6*(b-3)=10-2*(b+2)

83+5*(y-3)=3*(8y-9)

Answer 1

6*(b-3)=10-2*(b+2)

6b-18=10-2b-4

6b+2b=6+18

8b=24

b=24/8=3

 

83+5*(y-3)=3*(8y-9)

83+5y-15=24y-27

5y+68=24y-27

24y-5y=68+27

19y=95

y=95/19=5

Answer 2

6b-18=10-2b+4

6b+2b=10-4+18

8b=24

b=3

83+5y-15=24y-27

5y-24y=-27-83+15

-19y=-95

y=95\19

y=5
