Question

x+y=o if x is taken as 2 what is y?
Then find x-y

Answer 1

Answer:

y = -2

x - y = 4

Step-by-step explanation:

Given that

x + y = 0

x is taken as 2

Then ;

y = ?

Substitute x value in the given equation

x + y = 0

2 + y = 0

y = -2

x - y = ?

x = 2 ; y = -2

2 - ( -2 )

2 + 2

Hence ;

x - y = 4
