Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Simplify each fraction in the equation.
  • Combine like terms involving x x on each side of the equation.
  • Isolate the variable x x to solve the equation.

Now, let's work through each step:

Step 1: Simplify the fractions:

  • 2814=2 \frac{28}{14} = 2
  • 168=2 \frac{16}{8} = 2
  • The equation becomes:
    38x+25719=19x7x+2 38x + 2 - \frac{57}{19} = 19x - 7x + 2

Step 2: Combine like terms and simplify the equation:

  • Simplify the right side:
    19x7x=12x 19x - 7x = 12x
  • The equation now is:
    38x+25719=12x+2 38x + 2 - \frac{57}{19} = 12x + 2
  • Eliminate the constant 2 2 from both sides:
    38x5719=12x 38x - \frac{57}{19} = 12x

Step 3: Isolate the variable x x :

  • Subtract 12x 12x from both sides:
    38x12x5719=0 38x - 12x - \frac{57}{19} = 0
  • The equation simplifies to:
    26x5719=0 26x - \frac{57}{19} = 0
  • Add 5719 \frac{57}{19} to both sides:
    26x=5719 26x = \frac{57}{19}
  • To isolate x x , divide both sides by 26 26 :
    x=5719×26 x = \frac{57}{19 \times 26}
  • Calculate 19×26=494 19 \times 26 = 494 , so:
    x=57494 x = \frac{57}{494}

Upon simplification, we find x=326 x = \frac{3}{26} .

Therefore, the solution to the problem is x=326 x = \frac{3}{26} .

Answer

326 \frac{3}{26}
