Step-by-step solution

To solve this problem, we will follow these steps:

  • Step 1: Multiply both sides of the equation by 4 to eliminate the fraction.
  • Step 2: Simplify the resulting equation.
  • Step 3: Solve for xx.

Let's work through these steps:

Step 1: Start with the equation:

14(x8)=1 \frac{1}{4}(x - 8) = 1

Multiply both sides by 4 to remove the fraction:

4×14(x8)=4×1 4 \times \frac{1}{4}(x - 8) = 4 \times 1

This simplifies to:

x8=4 x - 8 = 4

Step 2: To isolate xx, add 8 to both sides of the equation:

x8+8=4+8 x - 8 + 8 = 4 + 8

This results in:

x=12 x = 12

Therefore, the solution to the equation is x=12 x = 12 .
