Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the common denominator.
  • Step 2: Rewrite the equation with the common denominator.
  • Step 3: Combine like terms.
  • Step 4: Solve the simplified equation for x x .

Now, let's work through each step:

Step 1: The denominators of the fractions are 4, 3, and 6. The least common denominator is 12.

Step 2: Rewrite each term with the common denominator:

  • 14x=312x-\frac{1}{4}x = -\frac{3}{12}x
  • 23x=812x\frac{2}{3}x = \frac{8}{12}x
  • 16x=212x-\frac{1}{6}x = -\frac{2}{12}x

Step 3: Combine the fractions:

312x+812x212x=2-\frac{3}{12}x + \frac{8}{12}x - \frac{2}{12}x = 2

This simplifies to 312x=2\frac{3}{12}x = 2.

Step 4: Simplify and solve for x x :

Multiply both sides by 12 to clear the denominator:

3x=243x = 24

Divide both sides by 3:

x=8x = 8

Therefore, the solution to the problem is x=8 x = 8 .
