Answer 2

Answer:

$\sf\purple {\dfrac{x - 4}{7} - \dfrac{x + 4}{5} = \dfrac{x + 3}{7} }$

$\sf\blue \implies \green { \dfrac{5(x - 4) - 7(x + 4)}{35} = \dfrac{x + 3}{7} }$

$\sf\red \implies \orange{ \dfrac{5x - 20 - 7x - 28}{35} = \dfrac{x + 3}{7} }$

$\sf\purple \implies \pink{ \dfrac{ - 2x - 48}{35} = \dfrac{x + 3}{7} }$

$\sf\green \implies \blue{ - 2x - 48 = \dfrac{x + 3}{7} \times 35}$

$\sf\orange \implies \red{ - 2x - 48 = (x + 3) \times 5}$

$\sf\pink \implies \purple{ - 2x - 48 = 5x + 15}$

$\sf\blue \implies \green{ - 7x = 63}$

$\sf\red \implies \orange{x = \cancel\dfrac{63}{ - 7} }$

$\sf\purple \therefore \pink{x = - 9}$
