Answer 1

Solution :

$\: \:$

$\sf:\implies \: (3x + 9) - (3x - 5) - (5x + 4) = 0 \\ \\ \\ \sf:\implies \: 3x + 9 - 3x + 5 - 5x - 4 = 0 \\ \\ \\ \sf:\implies \: 3x - 3x - 5x + 9 + 5 - 4 = 0 \\ \\ \\ \sf:\implies \: - 5x + 14 - 4 = 0 \\ \\ \\ \sf:\implies \: - 5x + 10 = 0 \\ \\ \\ \sf:\implies \: 5x = 10 \\ \\ \\ \sf:\implies \: x = \cancel\frac{10}{5} \\ \\ \\ \sf:\implies \: \underline{\boxed{\mathfrak\purple{x = 2}}} \: \bigstar \\ \\ \\ \\ \sf\therefore{\underline{Hence ,\: the \: value \: of \: x \: is \: \bold{2}.}}$
