Answer:
The expression "a - 2b + 3c" cannot be simplified further without knowing the specific values of variables a, b, and c.
Explanation:
The expression represents a linear combination of the variables a, b, and c. To simplify it, you would need to have specific values assigned to these variables. Once you know the values, you can substitute them into the expression and perform the arithmetic operations.
For example, if a = 4, b = 2, and c = 1, then the expression would simplify to:
4 - 2(2) + 3(1) = 4 - 4 + 3 = 3
However, without the values of a, b, and c, we cannot determine a specific numerical answer for the expression "a - 2b + 3c".
