The elements found in greatest abundance in the Earth include oxygen, silicon, aluminum, iron and calcium; these substances also make up the bulk of the moon. Although the moon is a<span>n airless world, it has large amounts of oxygen in the form of solid chemical compounds.</span>
X+y=4 :x=4-y,yR
x-y=6:x=6+y,yR
Answer:
The answer is x=9 so, its option 3.
