# Simultaneous Equation
# Write a program which solve a simultaneous equation:
#
# ax+by=c
# dx+ey=f
#
# The program should print x and y for given a, b, c, d, e and f (-1,000 ??? a,b,c,d,e,f ??? 1,000). You can suppose that given equation has a unique solution.
#
# Input
# The input consists of several data sets, 1 line for each data set. In a data set, there will be a,b,c,d,e,f separated by a single space. The input terminates with EOF.
#
# Output
# For each data set, print x and y separated by a single space. Print the solution to three places of decimals. Round off the solution to three decimal places.
#
# Sample Input 1
# 1 2 3 4 5 6
# 2 -1 -2 -1 -1 -5
# Output for the Sample Input 1
# -1.000 2.000
