Step-by-step solution

To solve this problem, we will proceed with the following steps:

  • Step 1: Start with the given equation: 14(x2)=3-\frac{1}{4}(x-2)=3.
  • Step 2: Multiply both sides by -4 to eliminate the fraction: (4)×14(x2)=(4)×3(-4) \times -\frac{1}{4}(x-2) = (-4) \times 3.
  • Step 3: Simplify: (x2)=12(x-2) = -12.
  • Step 4: Solve for xx by adding 2 to both sides: x=12+2x = -12 + 2.
  • Step 5: Simplify to find the value of xx: x=10x = -10.

Therefore, the solution to the equation is x=10x = -10.

According to the multiple-choice options, the correct answer is choice 2: -10.
