Answer 1

Answer:

6x-4y=-12 (equation 1)

8x-3y=-2 (equation 2)

now eliminate these equations

1st equation complete multiple by 6

2nd equation complete multiple by 8

then we get,

48x-32y=-96

48x-18y=-12

-. +. +.

${ change sign}$

-14y=-84

minus minus cancel

14y=84

now divide it

y=84/14

y=6

now put the value of y in equation 2

8x-3y=-2

8x-3*6=-2

8x-18=-2

8x=-2+18

8x=16

x=16/8

x=2

x=2, y=6
