x + y = 2x - 15
x = 2y - 5
y = (x + 5) / 2
x + (x + 5) / 2 = 2x - 15
x + 0.5x + 2.5 = 2x - 15
1.5x - 2x + 15 + 2.5 = 0
-.5x + 17.5 = 0
x = -17.5 / -.5
x = 35
x + y = 2x - 15
35 + y = 70 - 15
y = 55 - 35
y = 20

How can you decide if the difference of two numbers is positive negative or zero without actually calculating the difference?
You can do this by inspection. If the second number is smaller than the first, their difference is positive. If the second number is greater than the first, then their difference is negative. If the second number is the same as the first number, then their difference is zero.

The difference between two negative numbers is negative if?
The difference between two negative numbers is negative if the second number ( the number you are subtracting from the first) is less in value than the first. For example (-3) - ( -2) = -3 + 2 = -1 (-3) - (-4) = -3 + 4 = + 1

WHOEVER ANSWERED THIS PREVIOUSLY HAS NO IDEA WHAT WE ARE ALL TALKIN ABOUT , OBVIOUSLY * * * * * Ok, here is someone who might know. If the first number is bigger than the second, the difference is positive; If the first number is the same as the second, the difference is zero; and If the first number is smaller than the second, the difference is negative.
