x-4y=-5
solve in elimination method
​

Answer 1

Answer:

x+5y=13

x-4y=-5

change the sign

then the ans will be

9y=18

y=2

sub y=2in equation 2

x-8=-5

x=3

Answer 2

hope this helps u

given

x+5y = 13

x-4y =  - 5

i am eliminating  x here

so

x+5y = 13

x -4y = - 5

(-)   (+)    (+)

9y = 18

y = 18/9

y =2

  x+5y = 13

x = 13-5y

   = 13 - 5*2

     = 13-10

x= 3

so x = 3, y= 2
