You have the equation:

$a(0.08) + b(0.12) = 2200$

This equation represents a linear relationship between variables $a$ and $b$. However, since there is only one equation with two variables, we cannot determine unique values for $a$ and $b$ without additional information or another equation.

Would you like to solve for one variable in terms of the other, or do you have more equations to work with?

Related Questions:

1. What do $a$ and $b$ represent in this equation?
2. Do you have another equation involving $a$ and $b$?
3. Are you solving a mixture or investment problem?
4. Would you like the equation to be graphed?
5. Can you provide boundary conditions for $a$ and $b$?

Tip:

When dealing with multiple unknowns, you generally need as many independent equations as you have variables to find a unique solution.
