Question

How to solve all fraction algebra?

Answer 1

Answer:

$- \frac{1}{5} - \frac{4}{9} a = \frac{2}{15}$

$- \frac{4}{9} a = \frac{2}{15} + \frac{1}{5} \\ \\ - \frac{4}{9} a = \frac{1}{3 } \\ \\ ( - 4 \times 3)a = (1 \times 9) \\ - 12a = 9 \\ a = - \frac{9}{12} \\ \\ { \underline{ \: \: a = - \frac{3}{4} \: \: }}$
