Answer 1

Answer:

$x = 8$

Step-by-step explanation:

$\frac{x + 6}{4} + \frac{x - 3}{5} = \frac{5x - 4}{8}$

Take the LCM of the Denominators:

$\frac{5(x + 6)}{20} + \frac{4(x - 3)}{20} = \frac{5x - 4}{8}$

$\frac{5x + 30 + 4x - 12}{20} = \frac{5x - 4}{8}$

$\frac{9x + 18}{20} = \frac{5x - 4}{8}$

Cross multiply:

$8(9x + 18) = 20(5x - 4)$

$72x + 144 = 100x - 80$

$100x-72x = 144 + 80$

$28x = 224$

∴ $x = 8$
