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 using the substitution method and state if the system has a solution.
4p-2q=16
5p+7q=1
