Final answer:
The value of 2c - 3D when c = 6 and d = 4, assuming D is a typo for d, is 0.
Step-by-step explanation:
To find the value of 2c - 3D when c = 6 and d = 4, we need to substitute the given values into the equation. It is essential to note the difference in case sensitivity, as the variable D is not the same as d. Since D was not provided, we'll assume it is a typo and should actually be d. After substituting the values, we get:
2c - 3d = 2(6) - 3(4) = 12 - 12 = 0
The result of the equation is 0.
