ln(y)+ln(y+3)=ln(20-5y)

ln (y) + ln (y + 3) = ln (20 - 5 y)

y = 2

Solution steps

ln (y) + ln (y + 3) = ln (20 - 5 y)

Apply log rules

y (y + 3) = 20 - 5 y

Solve

y (y + 3) = 20 - 5 y : y = 2, y = - 10

y = 2, y = - 10

Verify Solutions:

y = 2

True

, y = - 10

False

The solution is

y = 2

y, 2 ln (x) = ln (y)

lo g_{x} (3) = 3

lo g_{2} (m x) = c

lo g_{10} (\frac{2 x - 4}{5}) = 2

0.64 = ln (y)
