Question

evaluate the expression when c = 6 and y = -3. -c + 2y

Explanation:

Step1: Substitute the values

Substitute \( c = 6 \) and \( y=-3 \) into the expression \( -c + 2y \). So we get \( -6+2\times(-3) \).

Step2: Perform the multiplication

Calculate \( 2\times(-3)= -6 \). Now the expression becomes \( -6+(-6) \).

Step3: Perform the addition

Add \( -6 \) and \( -6 \), which is \( -12 \).

Answer:

\(-12\)
