Step-by-Step Solution

To solve the equation 14x3=5+34x\frac{1}{4}x - 3 = 5 + \frac{3}{4}x, follow these steps:

  • Step 1: Eliminate 34x\frac{3}{4}x from the right side by subtracting 34x\frac{3}{4}x from both sides.

This gives:

14x34x3=5\frac{1}{4}x - \frac{3}{4}x - 3 = 5

  • Step 2: Combine the like terms xx on the left side.

This simplifies to:

24x3=5-\frac{2}{4}x - 3 = 5

or more simply,

12x3=5-\frac{1}{2}x - 3 = 5

  • Step 3: Add 3 to both sides to move the constant term.

This results in:

12x=8-\frac{1}{2}x = 8

  • Step 4: Solve for xx by multiplying both sides by 2-2 (the reciprocal of 12-\frac{1}{2}).

This yields:

x=16x = -16

Therefore, the solution to the equation is x=16 x = -16 .

Answer

16 -16
