Question

order of operations

i need the answer to x and y

thank you for helping😊

Answer 1

-5x-4y=23 ....... eq 1 and 2x-4y=2..........eq 2,

Subtracting eq 2 from 1,

-5x-4y=23

-2x+4y=-2

-7x =21

  x=-3

substiuting value of y in eq 2 , we get

2(-3)-4y =2

-6-4y=2

-4y=8

y=-2

(-3,-2)  , check your ans.
