Question

evaluate the expression when c=2 and x=-4. x - 7c

Explanation:

Step1: Substitute the values of c and x

We know that \( c = 2 \) and \( x=-4 \). Substitute these values into the expression \( x - 7c \).
So we get \( -4-7\times2 \).

Step2: Perform the multiplication first

According to the order of operations (PEMDAS/BODMAS), we multiply first. \( 7\times2 = 14 \). Now the expression becomes \( -4 - 14 \).

Step3: Perform the subtraction

Subtract 14 from -4. \( -4-14=-18 \).

Answer:

\( -18 \)
