Question

x+y=2 and 2x-3y=9 solve. ​

Answer 1

Answer:

x=3

y=-1

Step-by-step explanation:

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

2x-3y=9------(2)

multiply by eq. 1 by 3

3x+3y=6------(3)

now subtract eq.2 by 3

3x+3y=6

2x-3y=9

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

5x=15

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

x=3

x+y=2

3+y=2

y=2-3

y=-1

Answer 2

Answer:

Step-by-step explanation:

X+Y=2  ----- (1)

2X-3Y=9 ---(2)

MULTIPLY 3 IN EQUATION 1

3X+3Y=6 ------(3)

  (2)+(3)

5X=15

X=3

PUT X=3 IN EQUATION 2

WE GET , 6-3Y=9

3Y= -3

Y=-1

HENCE, X=3 AND Y=-1 IS THE SOLUTION
