2(x+y)=5
This equation is telling us that if we take any two numbers, x and y, and add them together, then multiply the result by 2, we will get 5. So, for example, if we take the numbers 3 and 2, and add them together to get 5, and then multiply that by 2, we will get 10.
This equation is actually quite interesting, because it is telling us something about the relationship between numbers that we might not have thought of before. It is also telling us that if we want to solve for x or y, we can do so by using some simple algebra.
To solve for x, we can start by isolating it on one side of the equation:
2x+2y=5
2y=5-2x
y=(5-2x)/2
Now we can plug this value for y back into the original equation:
2x+2y=5
2x+2((5-2x)/2)=5
2x+5-4x=5
-2x=5-5
-2x=-0
x=0
