the answer is y minus 10 divided by 2.
Suppose the numbers are x and y Then the sum of their reciprocals is 1/x + 1/y = y/xy + x/xy = (y+x)/xy = 10/20 = 1/2
2(2+Y)
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
x = 10, y = 25
To find 2 times the sum of y and 5, you first need to calculate the sum of y and 5 by adding y and 5 together. Once you have the sum, you then multiply it by 2 to find the final result. The expression for this calculation would be 2(y + 5).

2x / (y-2) + 2x / (2-y)First get a common denominator: (y-2) (2-y)Then you have:2x(2-y) / (y-2)(2-y) + 2x(y-2) / (y-2)(2-y), summing and simplifying, you get:(4x-4) / (y-2)(2-y)
1/x + 1/y y/xy + x/xy (y+x)/xy= 10/20 10/20=1/2 1/2 is the answer.
the answer is y minus 10 divided by 2.
x+y=18x^2+y^2=164 x=10 and y=8 or vice versa
Suppose the numbers are x and y Then the sum of their reciprocals is 1/x + 1/y = y/xy + x/xy = (y+x)/xy = 10/20 = 1/2

Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
2(2+Y)
Well, isn't that a happy little math problem we have here! When we divide y by 2, we're essentially splitting y into two equal parts. It's like sharing a delicious cake with a friend - each person gets half! So, y divided by 2 is simply y divided into two equal pieces.
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
