Final answer:
The expression is 2m + 3n - 6. Plugging in the values of m and n, we get 2(8) + 3(-5) - 6, 16 - 15 - 6. Now, we combine the like terms: 1 - 6 = -5. Therefore, the value of the expression 2m + 3n - 6 given m = 8 and n = -5 is -5.
Step-by-step explanation:
Evaluating the expression (2m + 3n - 6) with (m = 8) and (n = -5) involves substituting these values. The calculation, 2 times 8 plus 3 times -5 minus 6, simplifies to 1 minus 6. This combination of terms results in a final value of -5. Therefore, when applying the given numerical values to the expression, the outcome is -5, reflecting the specific arithmetic result without explicitly stating the equation.
