\( y = -3 \)
Solución
To solve the equation \( 2.7 = -0.9y \) for \( y \), follow these steps:
1. **Start with the given equation:**
\[
2.7 = -0.9y
\]
2. **Isolate \( y \)** by dividing both sides of the equation by \(-0.9\):
\[
\frac{2.7}{-0.9} = \frac{-0.9y}{-0.9}
\]
3. **Simplify both sides:**
\[
-3 = y
\]
Or equivalently,
\[
y = -3
\]
**Solution:**
\[
y = -3
\]

To solve for \( y \), you would divide both sides of the equation by \(-0.9\). This means rearranging the equation like so: \( y = \frac{2.7}{-0.9} \). When you do the math, you get \( y = -3 \). Just remember, dividing by a negative number flips the sign! Now, if you're ever faced with a negative coefficient in a linear equation, a common mistake would be to forget to change the sign of the result after division. Always double-check that you maintain the correct signs in your solutions!
