Question

solve the following simultaneous equation x+y=9,. x-y=3. ans me fast yaar​

Answer 1

Answer:

x+y = 9

=> x= 9–y —— (1)

Now, x–y = 3

=> (9–y)–y = 3 —(putting the value of x from equation 1)

=> 9–2y = 3

=> 2y = 9–3

=> 2y = 6

=> y = 3

From, equation (1) we get,

x= 9–y

=> x = 9–3 = 6

So, x = 6 & y = 3
