Evaluating 3x53x - 5 when x=2x = -2

To evaluate the linear expression 3x53x - 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.
