Question

Please help resolve the 8th one

Answer 1

Answer:

$\frac{ 2x - \frac{3}{4} }{3x + \frac{4}{5} } = \frac{1}{5}$

$\frac{ \frac{8x - 3}{4} }{ \frac{15x + 4}{5} } = \frac{1}{5}$

$\frac{8x - 3}{4} \times \frac{5}{15x + 4} = \frac{1}{5}$

$\frac{5(8x - 3)}{4(15x + 4)} = \frac{1}{5}$

$\frac{40x - 15}{60x + 16} = \frac{1}{5}$

$5(40x - 15) = 1(60x + 16)$

$200x - 75 = 60x + 16$

$200x - 60x = 16 + 75$

$140x = 91$

$x = \frac{91}{140} = \frac{13}{20}$
