Solve the following system of equations by the substitution method. Check the solution(s). \[ \begin{array}{l}x-4 y=7 \\ -4 x+16 y=-28\end{array} \] Select the correct choice below and, if necessary, fill in the answer box to complete your answer. A. There is one solution. The solution set is \( \left\{\begin{array}{l}\text { (Simplify your answer. Type an ordered pair.) }\end{array}\right. \) B. The system is dependent. The solution set is the set of all ordered pairs \( \{(x, \square)\} \), where \( x \) is any real number. (Simplify your answer. Type an expression using \( x \) as the variable. Use integers or fractions for any numbers in the expression.) The system is inconsistent.
