_ _ _ _ _ _ _ _ _ _ _ _ _ _ _✍️

$= > 8x + \frac{7}{9} = 9x - \frac{6}{5} - \frac{7}{8}$

=>On L.H.S L.C.M IS 9 and on R.H.S L.C.M IS 40.

$= > \frac{72x + 7}{9} = \frac{40 \times 9x - 6 \times 8 - 7 \times 5}{40}$

$= > \frac{72x + 7}{9} = \frac{360x - 48 - 35}{40}$

$= > \frac{72x + 7}{9} = \frac{360x - 83}{40}$

=>NOW ,We cross multiply .

$= > 40(72x + 7) = 9(360x - 83)$

=>After cross multiply we take variable one side and constant one side so that calculation will be made easy.

$= > 2880x + 280 = 3240x - 747$

$= > 1027 = 360x$

=>Now,here 1027 is being divided by 360

$= > x = \frac{1027}{360} = 2.85$
