Answer 2

$\tt\huge\purple{hello!!!}$

HERE IS UR ANSWER

$_____________________________$

1.

$\frac{x + 3}{2x + 5} = \frac{1}{3} \\ 3(x + 3) = 2x + 5 \\ 3x + 9 = 2x + 5 \\ x = 4$

2.

$\frac{2x - 1}{5x + 2} = \frac{2x + 3}{5x - 1} \\ (2x - 1)(5x - 1) = (2x + 3)(5x + 2) \\ 10x - 2x - 5x + 1 = 10x + 4x + 15x + 6 \\ - 7x - 19x = 6 - 1 \\ 26x = 5 \\ x = \frac{5}{26}$
