Look carefully at the point where the 2 lines intersect. From that point, look straight down to the x-axis; you'll see that the x-value there is 50. Similarly,
starting at the intersection, look straight left to the y-axis; the y-value there is 11.
Thus, the coordinates of the intersection (i. e., the solution) are found in (50,11).

Answer:
84ways
Step-by-step explanation:
This is a problem on combination. Combination has to do with selection. For example if r objects are to be selected from a pool of n objects, this can be done in nCr ways.
nCr = n!/(n-r)!r!
9C3= 9!/(9-3)!3!
9C3= 9!/(6)!3*2*1
9C3= 9*8*7*6!/(6)!6
9C3= 9*8*7*/6
9C3= 9*8*7*/6
9C3= 504/6
9C3= 84ways
