n = 3m - 11       2m + 3n = 0

Substitute the first equation into the value of n in the second equation:
2m + 3(3m - 11) = 0

Simplify:
2m + 9m - 33 = 0
11m - 33 = 0

Solve for m:
11m = 33
m = 3

Substitute the value of m into the first equation to find the value of n:
n = 3m - 11
n = 3(3) - 11
n = 9 - 11
n = -2

Solution: (-2,3)
