Question

113x - 212y = 14 , -212x + 113y = -311​

Answer 1

Step-by-step explanation:

113x=14+212y

x=14+212y/113..........(1)

-212(14+212y/113)+113y=-311

-212×(14/113)+{-212×(212y/113)=-311

answer will obtain by solving it

Answer 2

Step-by-step explanation:

-212x+113y=-311...........(1)

113x - 212y= 014...........(2)

_____________

-99x-99y = 297

-99(x+y). =297

x+y = -297÷99

x+y= -3

113x-212y=14.....×1

x + y = -3......×212 ( lcm of 212&1 is 212)

now we get,

113x - 212y=14

212x+212y= -636

______________

325x. = -622 therefore,x=1.913

x=1.913 substitute in equation 1

-212(1.913)+113y=-311

-405.556+113y=-311

113y =94.556

y=???????? it's wrong my answer???
