Question

2.
2x - 3y = 7
5x + y = 9​

Answer 1

Answer:

2x−3y=7 ----------------(1)

5x+y=9

y=9−5x-------------(2)

Now, substitute equation (2) in equation (1)

Then ,2x−3(9−5x)=7

2x−27+15x=7

17x=27+7

17x=34

x=34/17=2

y=9−5×2=9−10=−1

Therefore x is 2 and y is −1

Answer 2

Step-by-step explanation:

If u have to find the value of x

then,

2x-3y=7______(1)

5x+y=9_______(2)

eliminate equation (1)and (2),

multiplty equation (2)by 3,

15x+3y=27______(3)

add equation (1) and(2),

20x=36

x=36/20 = 9/5

5(9/5) +y=9

9+y=9

y=9

Hope it helps.. :)

put the value of x in equation (2)
