Question

x-y=0.9,11/2(x+y)=1​

Answer 1

Answer:

x= 3.2

y=2.3

Step-by-step explanation:

x-y = 0.9

--> Multiply by 10

10x - 10y = 9 ---→(a)

11/2(x+y) = 1

2(x+y) = 11

2x +2y = 11

--> Multiply by 5

10x + 10y = 55 --→(b)

Equation (a) + (b)

→ 20x = 64

x= 3.2

Equation (b) - (a)

⇒ 20y = 46

y= 2.3
