Question

2x+
3y = 9; 2x + y = 13​

Answer 1

Answer:

X=15/2 & y= -2

Step-by-step explanation:

2x+3y=9

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

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

By putting the value of 2x in (ii)

9-3y+y=13

=> -2y=13-9

=> -2y=4

=> y=4/-2

So, y = -2

By (i),

2x+3×(-2)=9

=> 2x-6=9

=> 2x=9+6

=> 2x=15

So,x=15/2

Therefore, x = 15/2 & y = -2 Ans.
