Question

2x-3y=9-------(1)
2x+y=13-------(2)​

Answer 1

Step-by-step explanation:

subtracting both the equation;

we get ;

-4y = -4

y = 1

substituting the value of 'y' in equation 1

2x -3 = 9

2x = 12

x = 6

Answer 2

Answer:

2x – 3y = 9 .....(I)

2x + y = 13 .....(II)

Subtracting (II) from (I) we get

– 3y − y = 9 − 13

⇒−4y=−4⇒y=1

Putting this value in (I) we get

2x−3(1)=9⇒2x=9+3=12⇒x=122=6

Thus, (x, y) = (6, 1)
