Question

$\frac{2}{5} y - \frac{5}{8} y = \frac{5}{12}$
​

Answer 1

Answer :-

$\frac{2}{5} y - \frac{5}{8} y = \frac{5}{12}$

$\mapsto \large y( \frac{16 - 25}{40}) = \frac{5}{12}$

$\mapsto \large \frac{ - 9}{40} y = \frac{5}{12}$

$\mapsto \large( - 9) \times y = \frac{5 \times 40}{12}$

$\mapsto \large \: y = \frac{5 \times 40}{12 \times ( - 9)}$

$\mapsto \large \: y = \frac{5 \times 10}{3 \times ( - 9)}$

$\mapsto \large \: y = \frac{50}{( - 27)}$

Since the denominator cannot be negative ,

$\mapsto \large \: y = \frac{( - 50)}{27}$
