hey mate :
given here
2x -7y = -10. ...(1)
3x + 2y = 10. ....(2)
multiply by 3 in (1) and 2 in (2)
we get ,
6x -21 y = -30. ...(3)
6x +4y = 20. ...(4)
equation (3) - (4)....
- 25 y = -50
y. = -50/-25
y= 2
put value of y in (1),
we get,
2x -7 × 2 = -10
2x =-10+14
2x = 4
x = 4/2
x = 2.
thus:
value of x and y will be
x= 2, y= 2
I hopes its help's u
follow me guess!!✌✌

Answer:
2x- 7y = - 10 _________(1)
3x + 2y = 10 __________(2)
multiplying by (1) 2 and by (2) 7
4x - 14y = -20
21x + 14y = 70
_______________
25x = 50
x = 2
putting the value (1)
2x-7 y =-10
2×2 - 7y =-10
4 -7y =-10
-7y= -10-4
-7y=-14
y=2
