\frac{5}{6} a + \frac{2}{5} = 1

a = - \frac{42}{25} or a = \frac{18}{25}

Solution steps

\frac{5}{6} a + \frac{2}{5} = 1

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{5}{6} a + \frac{2}{5} = - 1 or \frac{5}{6} a + \frac{2}{5} = 1

\frac{5}{6} a + \frac{2}{5} = - 1 or \frac{5}{6} a + \frac{2}{5} = 1

a = - \frac{42}{25} or a = \frac{18}{25}

ln (5) = y
