Question

solve for x and y equation 2x-7y=-10 and 3x+2y= 10​

Answer 1

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 2

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
