X=15 51/70

Answer 2

It seems like you're providing an equation, but there seems to be some confusion in the way you've written it. I'll do my best to interpret and solve it:

The equation you've written appears to be:

$(x-3,2) + \frac{4}{6/25} = 8 \frac{1}{2}$.

However, there are a few issues in the equation:

1. The comma (,) after "3" might not be intended. If you meant to subtract 3.2 from $x$, then you should use a hyphen or a minus sign instead of a comma.
2. The fraction $\frac{4}{6/25}$ needs to be simplified before adding it to the equation.
3. The mixed number $8 \frac{1}{2}$ should be converted to an improper fraction for consistent calculations.

Assuming you intended to write the equation in a more standard format, let's solve it step by step:

1. Convert the mixed number to an improper fraction: $8 \frac{1}{2} = \frac{17}{2}$.

2. Simplify the fraction: $\frac{4}{6/25} = \frac{4}{1} \times \frac{25}{6} = \frac{100}{6} = \frac{50}{3}$.

Now the equation becomes: $(x - 3.2) + \frac{50}{3} = \frac{17}{2}$.

3. To solve for $x$, isolate $x$ on one side of the equation: $(x - 3.2) = \frac{17}{2} - \frac{50}{3}$.

4. Find a common denominator for the fractions on the right side (which is 6): $\frac{17}{2} - \frac{50}{3} = \frac{51}{6} - \frac{100}{6} = -\frac{49}{6}$.

5. Substitute the value back into the equation: $x - 3.2 = -\frac{49}{6}$.

6. Solve for $x$: $x = -\frac{49}{6} + 3.2$, $x = \frac{-49 + 19.2}{6}$, $x = \frac{-29.8}{6}$, $x \approx -4.967$.

So, the solution to the equation is approximately $x \approx -4.967$.
