Question

(2) For simultaneous equations in variables x and y, Dx = 49, Dy = -63,D=7 then what is x ​

Savannah · Answer

Answer:   Given  DX= 49,Dy=-63  D=7  To find:x and y  solution : x= DX/D                    =49/7                x=7    Now                 y =Dy/D                   = -63/7                 y = -9

Emma · Answer

x = Dx/D     = 49/7     = 7    Therefore x = 7
