Final answer:
The restricted value of the expression (2)/(x-7) is x = 7.
Step-by-step explanation:
The expression given is (2)/(x-7). To identify the restricted values, we need to find the values of x that make the denominator equal to zero. Set the denominator x-7 equal to zero and solve for x:
Therefore, the restricted value is x = 7. This means that the expression is undefined when x = 7, as it would result in division by zero.
