Question

what is the value of x and y when X + Y is equal to 2 x minus Y is equal to 8​

Answer 1

Answer:

x = 5, y = -3

Step-by-step explanation:

x + y = 2

x - y = 8

Adding both the eqn.s, we get:

x + y = 2

x - y = 8

-------------

 2x = 10

 ∴ x = 5

Substituting x in the eqn., we get:

x + y = 2

5 + y = 2

∴  y = -3

Answer 2

Answer:

0

Step-by-step explanation:

x + y = 2x - y = 8

x + y = 2x - y

2x - x + y = y

x + x - x + y = y

x + y = y = 8

y = 8

x + 8 = 8

x = 0
