Answer:
To find the values of x and y in the expression (9x-7)(y+16) = m(7x+19)n^2, we need more information or the values of m and n.
Without knowing the specific values of m and n, we cannot determine the values of x and y. The equation contains variables (x and y) and constants (m and n), and we need to know the values of the constants in order to solve for the variables.
To find the specific values of x and y, we would need additional equations or information that relates to these variables. Without such information, the values of x and y remain unknown.
Therefore, in the given expression, we need more information or the values of m and n to find the specific values of x and y.
