Step-by-Step Solution

To solve the equation 61030x+14=6816x \frac{6}{10} - 30x + \frac{1}{4} = \frac{6}{8} - 16x , follow these steps:

  • Step 1: Simplify the fractions involved. We have 610=35 \frac{6}{10} = \frac{3}{5} and 68=34 \frac{6}{8} = \frac{3}{4} .
  • Step 2: The equation becomes 3530x+14=3416x \frac{3}{5} - 30x + \frac{1}{4} = \frac{3}{4} - 16x .
  • Step 3: Combine the constant terms on each side. The left side is 35+14\frac{3}{5} + \frac{1}{4}. Find a common denominator, which is 20:
  • 35=1220\frac{3}{5} = \frac{12}{20}
  • 14=520\frac{1}{4} = \frac{5}{20}
  • So, 35+14=1220+520=1720\frac{3}{5} + \frac{1}{4} = \frac{12}{20} + \frac{5}{20} = \frac{17}{20}.
  • Step 4: Substitute back into the equation: 172030x=3416x\frac{17}{20} - 30x = \frac{3}{4} - 16x.
  • Step 5: Simplify the right side. 34=1520\frac{3}{4} = \frac{15}{20}, so the equation becomes 172030x=152016x \frac{17}{20} - 30x = \frac{15}{20} - 16x .
  • Step 6: Subtract 1520\frac{15}{20} from both sides to get 1720152030x=16x\frac{17}{20} - \frac{15}{20} - 30x = -16x:
  • 17201520=220=110\frac{17}{20} - \frac{15}{20} = \frac{2}{20} = \frac{1}{10}.
  • So, the equation becomes 11030x=16x\frac{1}{10} - 30x = -16x.
  • Step 7: Rearrange the equation to solve for x x by adding 30x 30x to both sides: 110=30x16x\frac{1}{10} = 30x - 16x.
  • Step 8: Simplify the equation: 110=14x\frac{1}{10} = 14x.
  • Step 9: Divide both sides by 14 to solve for x x : x=110×14=1140 x = \frac{1}{10 \times 14} = \frac{1}{140}.

Therefore, the solution to the problem is x=1140 x = \frac{1}{140} .

Answer

1140 \frac{1}{140}
