Question

4x+5y=14&x-5y=16 =x=?
y=?​

Answer 1

Answer:

x = 6 and y = -2

Step-by-step explanation:

4x + 5y = 14   ...   (i)

x    - 5y  = 16   ...   (ii)

(i) + (ii)

⇒ 4x + x + 5y - 5y = 14 + 16

⇒ 5x = 30

⇒ x = 30 / 5

⇒ x = 6

Using x = 6 in (i)

(4 * 6) + 5y = 14  

24 + 5y = 14

5y = 14 - 24

5y = -10

y = -10 / 5

y = -2

So, x = 6 and y = -2

Answer 2

Answer:

X=6 ,Y= -2

Step-by-step explanation:

1) 4x+5y=14 ...(1)

2)x-5y=16 ...(2)

& summation of (1) and (2) -----

4x+5y=14

x- 5y=16

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

5x. =30

x = 6

and x=6 put on (2)---

x-5y=16

or, 6 -5y = 16

or, -5y=16-6

or, -5y =10

or, -y = 2

or, y= 2
