Answer 2

Let's solve each equation step by step:

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

   First, simplify the fractions: $\frac{X}{3} - 1 + \frac{X}{4} = -1$

   Next, get a common denominator, which is 12: $\frac{4X}{12} - \frac{12}{12} + \frac{3X}{12} = -1$

   Now, combine like terms: $\frac{4X + 3X - 12}{12} = -1$

   Simplify the numerator: $\frac{7X - 12}{12} = -1$

   Now, multiply both sides by 12 to isolate X: $7X - 12 = -12$

   Add 12 to both sides: $7X = 0$

   Finally, divide by 7 to solve for X: $X = 0$

2. $\frac{2X - 1}{4} - X + \frac{5}{12} = 13 + \frac{X}{2} - \frac{2X + 7}{3} = 22X + \frac{3}{3} - \frac{X - 1}{4} = 5$

   Let's solve each equation separately:

   a. $\frac{2X - 1}{4} - X + \frac{5}{12} = 13$

   First, get a common denominator, which is 12: $\frac{3(2X - 1)}{12} - \frac{12X}{12} + \frac{5}{12} = \frac{13(12)}{12}$

   Simplify: $\frac{3(2X - 1) - 12X + 5}{12} = \frac{156}{12}$

   Distribute the 3: $\frac{6X - 3 - 12X + 5}{12} = \frac{156}{12}$

   Combine like terms: $\frac{-6X + 2}{12} = \frac{156}{12}$

   Now, multiply both sides by 12 to isolate -6X + 2: $-6X + 2 = 156$

   Subtract 2 from both sides: $-6X = 154$

   Finally, divide by -6 to solve for X: $X = -\frac{154}{6} = -\frac{77}{3}$

   b. $\frac{X}{2} - \frac{2X + 7}{3} = 22X + 1 - \frac{X - 1}{4} = 5$

   First, simplify each fraction:

   $\frac{X}{2} - \frac{2X + 7}{3} = 22X + 1 - \frac{X - 1}{4} = 5$

   Now, get a common denominator, which is 12:

   $\frac{6X}{12} - \frac{8X + 28}{12} = \frac{22X \cdot 12 + 12}{12} - \frac{3(X - 1)}{12} = \frac{5 \cdot 12}{12}$
