Answer 1

$\huge \pink{Answer}$

$\frac{x}{5} + \frac{x}{3} + 7 = x \\ \\ \implies \frac{x}{5} + \frac{x}{3} - x = - 7 \: \: \: \: \: \: \\ \\ \implies \frac{3x + 5x - 15x}{15} = - 7 \\ \\ \implies \frac{ - 7x}{15} = - 7 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \implies x = \frac{ \cancel{- 7 } \times 15}{ \cancel{ - 7}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \implies \boxed{x = 15} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
