Question

solve for y if: 2(3y-4)+6/3y-(4+5y)=3/5

please help ​

Answer 1

Step-by-step explanation:

6y-8+2y-(4+5y)=3/5

6y-8+2y(-4-5y)=3/5

6y-8-8y-10y²=3/5

-10y²-2y-8=3/5

-2(5y²+y+4)=3/5

5y²+y+4=(3/5)/-2

5y²+y=-3/10-4

5y²+y=(-3-40)/10

5y²+y=-43/10

5y²+y+43/10=0

a=5,b=1,c=43/10

D=b²-4ac

1²-4×5×43/10

1-86

-85

y=(-b²+-√d)/2a

( 1+√85)/2×5
