Hi Adrianna,

10b+c is what is known as an **algebraic expression**. That means that your statement of value has at least one variable, and may have constants, coefficients, operations, other variables, etc.

From what you have given there is just not enough to find the value of 10b+c. At the very least, you would also need to know either:

- the value of the
*entire* expression and then you could find a relationship between the values of b and c
- values for
*both* b and c at which point you could "plug in" and evaluate.

I would be happy to help with this once you have provided enough additional information. Good luck.
