Question

Нужна помощь по алгебре!

Answer 1

6x-5(2x+8)>14+2x
6x-10x-40-14-2x>0
-6x-54>0
-6x>54
-x>9
x>-9

Answer 2

ой, в конце x<-9

Answer 3

((2a+2b)/b)*((1/(a-b))-(1/(a+b)))=
((2(a+b))/b)(((a+b)-(a-b)/(a+b)*(a-b))=
(2/b)*(2b/(a-b))=
2b/(a-b)

Answer 4

6x-5(2x+8)>14+2x

Answer 5

-6x>54

Answer 6

x<-9
