Question

solve following simultaneous equation 2x+y=5,3x-y=5​

Answer 1

Answer:

x = 2

y = 1

Step-by-step explanation:

2x + y = 5 -----------(1)

3x - y =  5

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

5x = 10

x = 2

substituting the value of x in (1)

y = 1

Answer 2

Answer:

Required value of x = 2 & y = 1

Step-by-step explanation:

2x + y = 5 ----------------(i)

3x - y = 5 -----------------(ii)

Now, adding (i) & (ii) , We get,

2x + y + 3x - y = 5 + 5

=> 5x = 10

=> x = 2

Putting the value of x = 2 in equation (i),

2*2 + y = 5

=> 4 + y = 5

=> y = 1
