Question

Solve 7y+4/y+2=-4/3 for y.

Answer 1

Answer:

7y+4/y+2=-4/3

7y^2+4+2y/y =-4/3

3(7y^2+4+2y)=-4y

27y^2+12+6y+4y=0

27y^2+10y+12=0

Answer 2

$\frac{7y + 4}{y + 2} = \frac{ - 4}{3}$

$= > 3(7y + 4) = - 4(y + 2)$

$= > 21 y+ 12 = - 4 y- 8$

$= > 21y + 4y = - 12 - 8$

$= > 25y = - 20$

$= > y = \frac{ - 20}{25}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{ - 4}{5}$
