Step-by-step solution

To solve the equation 16(x4)=14(13x+3) \frac{1}{6}(x-4) = \frac{1}{4}(\frac{1}{3}x+3) , follow these steps:

  • Step 1: Clear fractions by finding a common multiple.
    The least common multiple of 6 and 4 is 12. Multiply both sides by 12 to eliminate the fractions.
    12×(16)(x4)=12×(14)(13x+3) 12 \times \left( \frac{1}{6} \right)(x-4) = 12 \times \left( \frac{1}{4} \right)\left( \frac{1}{3}x + 3 \right) .
  • Step 2: Simplify both sides.
    On the left side: 2(x4)=2x8 2(x-4) = 2x - 8 .
    On the right side: 3(13x+3)=x+9 3\left( \frac{1}{3}x + 3 \right) = x + 9 .
  • Step 3: Set the simplified expressions equal.
    2x8=x+9 2x - 8 = x + 9 .
  • Step 4: Solve the linear equation for x x .
    Subtract x x from both sides: 2xx=9+8 2x - x = 9 + 8 .
    This simplifies to x=17 x = 17 .

Therefore, the solution to the equation is x=17 x = 17 .
