Responses

{x+y=531y=2x
A system of equations. Row one x plus y equals 531. Row 2 y equals 2 x

{x+y=2y=531x
A system of equations. Row one x plus y equals 8. Row 2 y = 531 x.

{x−y=531y=2x
A system of equations. Row one x minus y equals 531. Row 2 y = 2 x.

{x+2y=531y=2x
A system of equations. Row one x plus 8 y equals 531. Row 2 y = 8 x.

Answer 1

x+y=531
