2x- 4y=24


plz don't post irrelevant answer​

Answer 1

Answer:

x=-28

y=-13

Step-by-step explanation:

2x+3y=11 eqn1

2x-4y=24 eq2

consider equation 1

2x-3y=11

2x=11+3y

x=(11+3y)/2

substitute this into equation 2

2(11+3y)/2-4y=24

11+3y-4y=24

-y=24-11

y=-13

substitute y value now

2x-4y=24

2x-4(-13)=24

2x+52=24

2x=24-52

x=-28

Answer 2

Answer:

on solving above equations we get;

y= -13

and x= -28
