2/3(4/5 y + 3/6)=2/3(2/4 y- 3/5)

(4/5y+3/6)= (2/4y-3/5)

4/5y- 2/4y= -3/5- 3/6

4/5y- 1/2y= -3/5- 1/2

(4•2)/(5•2)y- (1•5)/(2•5)y= -(3•2)/(5•2)- (1•5)/(2•5)

8/10y- 5/10y= -6/10- 5/10

3/10y= -11/10

Y= -11/10: 3/10

Y= -11/10• 10/3

Y= -11/1• 1/3

Y=-11/3 = -3 2/3

_______________

2/3(4/5 y + 3/6)=2/3(2/4 y- 3/5)

2/3•(4/5• (-11/3)+ 1/2)= 2/3•(1/2• (-11/3)- 3/5)


2/3• ( -44/15+ 1/2)= 2/3• (-11/6 -3/5)

2/3•(-44/15)+2/3•1/2=2/3•(-11/6)-2/3•3/5


-88/45+ 1/3= (-22/18) -2/5

-88/45+ (1•15)/(3•15)= (-22•5)/(18•5)-(2•18)/(5•18)


-88/45+ 15/45= -110/90 -36/90


-(88/45-15/45)= -(110/90+36/90)

-73/45= -146/90

-73/45= -73/45

-1 28/45= -1 28/45
