Question

PLZ HELP, The sum of two numbers is 0.

Answer 1

Answer

y = -x

y = (3/2)x - 5

Explanation.
the sum of 2 numbers is 0
That will be,

x + y = 0

Adding x both sides we get, 
 y = -x

The other statements is,

3x - 2y = 10
Adding 2y on both sides we get,
3x = 10 + 2y

Subtracting 10 both sides we get,

2y = 3x - 10


Dividing both sides by 2 we get,

y = (3/2)x -5
