Understand Operation: Understand the operation to be performed. We need to subtract −2w from −6w. This means we are taking the value −6w and subtracting −2w from it.
Perform Subtraction: Perform the subtraction. Subtracting a negative is the same as adding its positive equivalent. So, −6w−(−2w) is the same as −6w+2w.
Combine Like Terms: Combine like terms. Since both terms involve the variable w, we can combine them by adding their coefficients.−6w+2w=(−6+2)w=−4w
