Step-by-step explanation:

i hope it will help u .....

Answer 2

Step-by-step explanation:

By using elimination method-

6x+4y=22. ....(1)

6x-9y+30

or, 6x-9y=-30. .....(2)

on subtracting eq (1) from eq(2)-

6x-9y= -30

6x+4y = 22

signs Will get changed

solution will be =

-13y = -52

y= 4

put the value of y in either eq (1) or eq (2)-

6x + 4x4 = 22

6x = 22-16

6x = 6

x = 1.
