Final answer:
To find the result when subtracting 1 from twice the value of C, multiply the value of C by 2 and then subtract 1.
Step-by-step explanation:
To find the result when subtracting 1 from twice the value of C, we can use the equation 2C - 1. This means we multiply the value of C by 2 and then subtract 1. For example, if C = 3, the calculation would be 2(3) - 1 = 6 - 1 = 5. Therefore, the result is 5.
