The process of evaluating an expression using specified values involves replacing the variables in the expression with the given values. To illustrate, consider you've been given the expression 2x + 3y and the values for x and y are 1 and 2 respectively. What you would do is substitute these values into the expression, resulting in 2*1 + 3*2. This further simplifies to give us 8.
