Solve using the substitution method and state if the system has a solution.
4p2q=16
5p+7q=1

4p  2q = 16
4p = 16 + 2q
p = 4 + .5q
5p + 7q = 1
Substitute 4 + .5q for p in the last equation and solve for q. Put that value in the previous equation to find p. Check by putting both values into the last equation. 
solve the system of equations answer as an ordered pair 5xy=27
