Best ResponseYou've already chosen the best response.0I will try to solve your system of equations. 3x−y=−4;x+y=0 Step: Solve 3x−y=−4 for y: 3x−y+−3x=−4+−3x(Add 3x to both sides) −y=−3x−4 (Divide both sides by 1) y=3x+4 Step: Substitute (3x+4) for y in x+y=0: x+y=0 x+3x+4=0 4x+4=0(Simplify both sides of the equation) 4x+4+−4=0+−4(Add 4 to both sides) (Divide both sides by 4) x=−1 Step: Substitute (−1) for x in y=3x+4: y=3x+4 y=(3)(−1)+4 y=1(Simplify both sides of the equation) Answer: y=1 and x=−1
