Question

plz solve this .......​

Answer 1

Answer:

x = 49/29

y = 19/29

Step-by-step explanation:

given that the equation,

7x - 15y = 2. ....(1)

x + 2y = 3. ....(2)

from equation (2)

x + 2y = 3

x = 3 - 2y

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

now,

putting the value of x from (3) on (1)

7x - 15y = 2

7(3 - 2y) - 15y = 2

21 - 14y - 15y = 2

-29y = 2 - 21

-29y = -19

y = -19/-29

y = 19/29

now,

From (3)

x = 3 - 2y

x = 3 - 2(19/29)

x = 3 - 38/29

x = 49/29

so,

x = 49/29

y = 19/29

Answer 2

Step-by-step explanation:

GIVEN EQUATION ,

7x-15y= 2...........(1)

x+2y= 3............(2)

FROM EQUATION (2)

x+2y= 3

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

NOW FINDING THE VALUE OF Y.

PUT VALUE OF X= 3-2Y IN EQUATION 1

7x-15y=2

7(3-2y)-15y= 2

21-14y-15y= 2

21-29y= 2

-29y= 2-21

-29y= -19

y=19/29

Put The Value of y in equation 3.

x=3-2y

x= 3-2(19/29)

x= 3-38/29

x=49/29
