Let two forces F1 = 2I + 3j + 6K and F2 = 2I + 4J + 2K act on point m (1, - 2,3), and point n (P, Q, 19) is on the action line of the resultant force P = 9q = 12 please give me a message

Let two forces F1 = 2I + 3j + 6K and F2 = 2I + 4J + 2K act on point m (1, - 2,3), and point n (P, Q, 19) is on the action line of the resultant force P = 9q = 12 please give me a message

The resultant force of F1 and F2 = 4I + 7J + 8K = (4,7,8) is collinear with MQ
MQ=(p-1,q+2,16)
So: MQ = m (4,7,8)
p-1=4m,q+2=7m ,16=8m
m=2
p=9,q=12
