## anonymous 5 years ago 1/y+5 + 3/5y can someone help me

1. anonymous

to add them, you need the same denominator. Therefore, we multiply 1/y+5 by 5y and 3/5y by y+5 So we get: (6y+5)/(5y^2+25y)

2. anonymous

$\frac{1}{y+5}+\frac{3}{5 y}=\frac{8 y+15}{5 y^2+25 y}$ Checks out with y evaluated at 31.
