Question: Solve for y:
Ax + By = C
y = \square
1. **State the problem:** We need to solve the linear equation $$Ax + By = C$$ for the variable $$y$$.
2. **Isolate the term with $$y$$:** Subtract $$Ax$$ from both sides to get:
$$Ax + By - Ax = C - Ax$$
which simplifies to
$$By = C - Ax$$
3. **Solve for $$y$$:** Divide both sides by $$B$$ to isolate $$y$$:
$$\frac{By}{\cancel{B}} = \frac{C - Ax}{\cancel{B}}$$
which simplifies to
$$y = \frac{C - Ax}{B}$$
4. **Final answer:**
$$\boxed{y = \frac{C - Ax}{B}}$$
This formula expresses $$y$$ in terms of $$x$$ and the constants $$A$$, $$B$$, and $$C$$. Remember, $$B$$ must not be zero for this division to be valid.
