Answer:
The solution is
Step-by-step explanation:
The given equations are
and
The graph of the two equations intersects at 
as show in the graph in the attachment.
The point of intersection of the two graphs is the solution to system of equations.
Hence the solution is
Number of red marbles in bag = r. b = 10-rProbability of first marble being red: r/10Second marble being red: (r-1)/9total probability = 2/15 = (r-1)*r/90r = 4b = 6
