At the beginning of World War I the number of troops on each side were extremely varied. The Central Powers consisted of the German Empire the Austro-Hungarian Empire the Ottoman Empire and Bulgaria. The Allied Powers consisted of Serbia Montenegro Belgium France Great Britain Japan Italy Portugal Romania Russia and the United States. The Central Powers had a combined total of about 21.5 million soldiers while the Allied Powers had around 28.5 million soldiers. This gave the Allied Powers a slight advantage in numbers but the Central Powers had a much higher ratio of soldiers to civilians. The Central Powers also had better trained and better equipped troops which allowed them to make up for the numerical difference in some areas of the conflict.

2x - 6 = 3Add 6 to each side:2x = 9Divide each side by 2:x = 4.5
2x + 7 = 13Subtract 7 from each side:2x = 6Divide each side by 2:x = 3
You can cross multiply if there are two fractions to compare. EXAMPLE: 1 2 If you multiply the lower right # __________ = __________ by the upper left # you will get 4 for 2 4 the left side and if you multiply the lower left by the upper right you will 4 also. compare the numbers for each side and you get "equal to"
9 + 3x = 45Subtract 9 from each side:3x = 36Divide each side by 3:x = 12
3x + 4 = 28Subtract 4 from each side:3x = 24Divide each side by 3:x = 8
