Step-by-Step Solution

Let's solve the equation 14x+3=12-\frac{1}{4}x + 3 = \frac{1}{2} following these steps:

  • Step 1: Subtract 3 from both sides to eliminate the constant on the left.

14x+33=123 -\frac{1}{4}x + 3 - 3 = \frac{1}{2} - 3

14x=123 -\frac{1}{4}x = \frac{1}{2} - 3

Simplifying the right side gives:

14x=52 -\frac{1}{4}x = -\frac{5}{2}

  • Step 2: Multiply both sides by 4-4 to isolate xx.

x=52×(4) x = -\frac{5}{2} \times (-4)

x=202 x = \frac{20}{2}

x=10 x = 10

Thus, we find the solution to be x=10 x = 10 .

Answer

10 10
