x = -3 and x = 21/2

Step-by-step explanation:

Case 1:

$\frac{X}{12} + \frac{1}{3} = \frac{1}{12}$

$\frac{X}{12} = \frac{1}{12} - \frac{1}{3}$

Now since the LCM of 12 and 3 is 12 therefore,

$\frac{X}{12} = \frac{1 - 4}{12}$

$\frac{X}{12} = - \frac{3}{12}$

$X = -\frac{3}{12} \times 12 = -3$

Case 2:

$\frac{X}{14} - \frac{1}{2} = \frac{1}{4}$

$\frac{X}{14} = \frac{1}{4} + \frac{1}{2}$

Since the LCM of 2 and y is 4, therefore

$\frac{X}{14} = \frac{1 + 2}{4}$

$\frac{X}{14} = \frac{3}{4}$

$X = \frac{3}{4} \times 14 = \frac{21}{2}$
