FranThe sum of 8 and y can be represented as 8 + y. This expression cannot be simplified further without knowing the specific value of y. In algebra, y is a variable that represents an unknown value, so the sum of 8 and y remains as 8 + y until y is given a specific numerical value.
'Sum' means 'Add'.
Algebraically this is written as '8 + y'. Done!!!!!

The second of two numbers is 8 more than 3 times the first Their sum is 72 find the numbers?
y = 3x+8 x + y = 72 x = 16 y = 56
What are two numbers whose sum is 52 and difference is 8?
Let this numbers be x and y, then x + y = 52 x - y = 8 x = 8 + y x + y = 52 substitute 8 + y for x into the first equation; 8 + y + y = 52 8 + 2y = 52 subtract 8 to both sides; 2y = 44 divide by 2 to both sides; y = 22 x = 8 + y substitute 22 for y into the equation; x = 8 + 22 x = 30 Thus this numbers are 22 and 30. 22 & 30
