Answer
\( a = -13 \)
Solution
Para resolver la ecuación \( 33 = -2a + 7 \) y encontrar el valor de \( a \), sigue estos pasos:
1. **Aísla el término que contiene a \( a \):**
\[
33 = -2a + 7
\]
Resta 7 de ambos lados de la ecuación para despejar el término con \( a \):
\[
33 - 7 = -2a
\]
\[
26 = -2a
\]
2. **Despeja \( a \):**
Divide ambos lados de la ecuación entre -2 para encontrar el valor de \( a \):
\[
\frac{26}{-2} = a
\]
\[
a = -13
\]
**Respuesta:** \( a = -13 \)

Simplify this solution Bonus Knowledge
To solve for \( a \), let's first get all terms involving \( a \) on one side. Start by subtracting 7 from both sides: \[ 33 - 7 = -2a \] This simplifies to: \[ 26 = -2a \] Next, divide both sides by -2 to isolate \( a \): \[ a = \frac{26}{-2} \] Thus, you get: \[ a = -13 \] And there you have it! \( a = -13 \). That wasn't too tricky, was it?
