To solve the equation $B = my + x$ for $m$, follow these steps:

1. Subtract $x$ from both sides of the equation: $B - x = my$

2. Now, divide both sides of the equation by $y$ to isolate $m$: $m = \frac{B - x}{y}$

Thus, the solution for $m$ is: $m = \frac{B - x}{y}$

Would you like further clarification on this solution? Here are some related questions:

1. How would you solve for $y$ in the equation $B = my + x$?
2. What happens if $y = 0$ in this equation?
3. How can you graph this equation in terms of $m$ and $B$?
4. How does changing $x$ affect the value of $m$?
5. What other methods can be used to solve for a variable in a linear equation?

Tip: Always check the constraints before solving; for instance, if any denominator can be zero, the equation becomes undefined.
