Evaluating 3x−53x - 5 when x=−2x = -2

To evaluate the linear expression 3x−53x - 5 when x=−2x = -2, substitute −2-2 for the variable xx and simplify using the order of operations. First, replace xx with −2-2 using parentheses to get 3(−2)−53(-2) - 5. Next, multiply 33 by −2-2 to obtain −6-6. Finally, subtract 55 from −6-6, which is equivalent to adding −5-5 to −6-6, resulting in −11-11. This example demonstrates substituting a negative integer into a linear expression.
