Question

if 8x-4/12 - 24x-8/20 = 1/3 then find the value of 'x'

Answer 1

the answer is equals to 0.75

Answer 2

Answer:

The value of 'x' is -1/2.

Given:

(8x - 4)/12 - (24x - 8)/20 = 1/3

Find:

The value of 'x'.

Solution:

Given equation is,

(8x - 4)/12 - (24x - 8)/20 = 1/3

$\frac{8x - 4}{12} -\frac{24x - 8}{20} = 1/3$

LCM of 12 and 20 is 60.

$\frac{5(8x - 4) - 3(24x - 8)}{60} = 1/3\\\\\frac{40x - 20 - 72x + 24}{60} = \frac{1}{3} \\\\\frac{4 - 32x }{60} = \frac{1}{3}\\\\3(4-32x) = 60\\\\12 - 96x = 60\\\\96x = 12 - 60\\\\96x = -48`\\\\x = -48/96\\\\x = -1/2$

Hence, the value of x = -1/2.
