Solve for x in the equation −6.29(x+7.85)=−19.499 .

1 answer

To solve the equation \(-6.29(x + 7.85) = -19.499\), we'll start by simplifying and isolating \(x\).

  1. Distribute \(-6.29\) on the left side:

\[ -6.29x - 6.29 \cdot 7.85 = -19.499 \]

Calculating \(-6.29 \cdot 7.85\):

\[ -6.29 \cdot 7.85 \approx -49.2905 \]

So the equation becomes:

\[ -6.29x - 49.2905 = -19.499 \]

  1. Add \(49.2905\) to both sides to isolate the term with \(x\):

\[ -6.29x = -19.499 + 49.2905 \]

Calculating the right side:

\[ -19.499 + 49.2905 \approx 29.7915 \]

Now we have:

\[ -6.29x = 29.7915 \]

  1. Next, divide both sides by \(-6.29\):

\[ x = \frac{29.7915}{-6.29} \]

Calculating this gives:

\[ x \approx -4.74 \]

Thus, the solution for \(x\) is:

\[ \boxed{-4.74} \]
