are there separate questions
OpenStudy (anonymous):
begin by solving for x or y in one of the equations, it will be in terms of the other variable
OpenStudy (dtan5457):
5x-3y=-13 25x-y=-14 I would take the second equation and make it -y=-14-25x which becomes y=14+25x Now just plug y=14+25x into the y value of 5x-3y=-13
