Question

if 19x+26y =250and 26x+19=200. find x+y ​

Answer 1

Answer:

19x+26y=250     (1)

26x+19y=200     (2)

Adding eq 1 and 2

26x+19y=200

+(19x+26y)=250

⇒45x+45y= 450

⇒45(x+y)= 45*10

⇒x+y=10

Answer 2

Answer:

x = 181 / 26 and y = 3061 / 276 . So , x + y = 181 / 26 + 3061 / 276 = 7767 / 26.

Step-by-step explanation:

According to the question ,

=> 26x + 19 = 200

=> 26x = 200 - 19

=> 26x = 181

=> x = 181 / 26

According to the question ,

=> 19x + 26y = 250

=> 19 * 181 / 26 + 26y = 250

=> 3439 / 26 + 26y = 250

=> 26y = 250 - 3439 / 26

=> 26y = 3061 / 26

=> y = 3061 / 26 * 1 / 26

=> y = 3061 / 276

So , x + y = 181 / 26 + 3061 / 276 =

181 * 26 / 26 * 26 + 3061 / 276 =

4706 / 26 + 3061 / 276 =

7767 / 26 = x + y

I hope this answer helps you !
