Question

1.Solve 2x+5y=12; 3x-y=1

Answer 1

⭐Hey here is your answer..⭐

2x + 5y = 12

3x - y = 1

=> 3x - 1 = y ..........(1)



2x + 5y = 12

2x + 5(3x - 1) = 12. ( from 1 y = 3x - 1)


2x + 15x - 5 = 12


17x = 12 + 5

17x = 17

x = 17/17

x = 1



Putting the value of x in eq. 1


3x - 1 = y

(3×1) - 1 = y

3 - 1 = y

2 = y



therefore value of x = 1 and y = 2



I HOPE IT HELP WILL YOU ☺️☺️


Thnx for asking ur question ✌️✌️

Answer 2

HELLO DEAR,

2x + 5y = 12-----------( 1 )
3x - y = 1 ---------------( 2 )

from------( 1 ) & ( 2 )
multiply by ( 5 ) *in ---( 2 )

2x + 5y = 12
15x - 5y = 5
-------------------
17x = 17

x = 17/17

x = 1 [ put in ( 1 ) ]

we get,

2(1) + 5y = 12

5y = 12 - 2

y = 10/2

y = 5

I HOPE ITS HELP YOU DEAR,
THANKS
