In mathematics, "y plus 3" is an algebraic expression representing the sum of a variable 'y' and the constant 3. This expression cannot be simplified further unless the value of 'y' is known. If 'y' is a known value, then the sum can be calculated by adding 3 to that value. If 'y' is unknown, then the expression "y + 3" remains as is, representing a sum of 'y' and 3.
It is (x + y)^3 - sqrt(5x + 3y) and there is no sensible simplification of this expression.
The word sum is the clue. It means the problem will be an addition problem.y + 3(8) = ?y + 24 = ?
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
y is 2 less than the product of 3 and x

3x over x + y
Suppose the numbers are x and y. The sum of their reciprocals = 1/x + 1/y = y/xy + x/xy = (y+x)/xy = (x+y)/xy = 10/30 = 1/3
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
y is 2 less than the product of 3 and x
