plz give correct answer if you know whenever don't answer​

Answer 1

Answer:

$\frac{2x - 3}{5} + \frac{x + 3}{4} = \frac{4x + 1}{7} \\ \therefore \: \frac{4(2x - 3) + 5(x + 3)}{5 \times 4} = \frac{4x + 1}{7} \\ \therefore \: \frac{8x - 12 + 5x + 15}{20} = \frac{4x + 1}{7} \\ \therefore \: \frac{13x + 3}{20} = \frac{4x + 1}{7} \\ \therefore \: 7(13x + 3) = 20(4x + 1) \\ \therefore \:91x + 21 = 80x + 20 \\ \therefore \:91x - 80x = 20 - 21 \\ \therefore \:11x = - 1 \\ \implies \huge \boxed{ x = - \frac{1}{11} }$
