Step-by-Step Solution

To solve the equation y423=8 y - 4\frac{2}{3} = 8 , follow these steps:

  • Step 1: Identify the given equation:
    y423=8 y - 4\frac{2}{3} = 8 .
  • Step 2: Solve for y y by eliminating the subtraction of 423 4\frac{2}{3} . We do this by adding 423 4\frac{2}{3} to both sides of the equation:
    y423+423=8+423 y - 4\frac{2}{3} + 4\frac{2}{3} = 8 + 4\frac{2}{3} .
  • Step 3: Simplify the left side:
    Since 423423=0 4\frac{2}{3} - 4\frac{2}{3} = 0 , the left side simplifies to just y y .
    Thus, y=8+423 y = 8 + 4\frac{2}{3} .
  • Step 4: Simplify the right side by converting the mixed number to an improper fraction:
    Convert 423 4\frac{2}{3} to an improper fraction: Multiply 4 by 3 and add 2, giving 143 \frac{14}{3} .
    Therefore, add 8+143 8 + \frac{14}{3} . Convert 8 to a fraction with denominator 3, which is 243 \frac{24}{3} .
    Now, add these fractions:
    243+143=383 \frac{24}{3} + \frac{14}{3} = \frac{38}{3} .
  • Step 5: Convert back to a mixed number (if desired):
    383=1223 \frac{38}{3} = 12\frac{2}{3} .

Therefore, the solution to the problem is y=1223 y = 12\frac{2}{3} .

Answer

1223 12\frac{2}{3}
