Answer
\( w = 5 \)
Solution
Solve the equation \( \frac{5}{4}=\frac{15}{w+7} \).
Solve the equation by following steps:
- step0: Solve for \(w\):
\(\frac{5}{4}=\frac{15}{w+7}\)
- step1: Find the domain:
\(\frac{5}{4}=\frac{15}{w+7},w\neq -7\)
- step2: Swap the sides:
\(\frac{15}{w+7}=\frac{5}{4}\)
- step3: Rewrite the expression:
\(w+7=\frac{15\times 4}{5}\)
- step4: Divide the terms:
\(w+7=12\)
- step5: Move the constant to the right side:
\(w=12-7\)
- step6: Subtract the numbers:
\(w=5\)
- step7: Check if the solution is in the defined range:
\(w=5,w\neq -7\)
- step8: Find the intersection:
\(w=5\)
La solución para \( w \) es \( w = 5 \).

The Deep Dive
Para resolver la ecuación \( \frac{5}{4}=\frac{15}{w+7} \), primero multiplicamos en cruz: \[ 5(w + 7) = 4 \cdot 15 \] Esto se simplifica a: \[ 5w + 35 = 60 \] Ahora, restamos 35 de ambos lados: \[ 5w = 60 - 35 \] \[ 5w = 25 \] Dividimos entre 5: \[ w = \frac{25}{5} = 5 \] Por lo tanto, la solución es \( w = 5 \).
