 Question 272146: Solve the system of equations using the Addition/Elimination Method. x – 3y = 3 0.5x + 2y = –0.25 Found 3 solutions by Tobiasz, Alan3354, richwmiller:Answer by Tobiasz(54)   (Show Source): You can put this solution on YOUR website!-0.5(x – 3y = 3 ) 0.5x + 2y = –0.25 -0.5x - 1.5y = 1.5 Should be -0.5x + 1.5y = 1.5 0.5 + 2y = -0.25 0.5y = 1.25 <---- divide both by 0.5 <--- plug this in any equation and you get x - 2.5 = 3 (0.5,2.5) ---------- Check: x – 3y = 3 0.5 - 3*2.5 =? 3 -7 =? 3 No. -------------- 0.5x + 2y = –0.25 0.5*0.5 + 2*2.5 =? -0.25 .25 + 5 =? -0.25 No --------------------- So it's wrong. Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!x – 3y = 3 0.5x + 2y = –0.25 --> -x - 4y = 0.5 ------------------ -x -4y = 0.5 x – 3y = 3 ---------------- Add -7y = 3.5 y = -0.5 ---------- x = 1.5 Answer by richwmiller(9143)   (Show Source): You can put this solution on YOUR website!x=1.5, y~-0.5 x – 3y = 3 0.5x + 2y = –0.25 multiply second by 2 x-3y=3 x+4y=-.5 subtract second from first -7y=3.5 y=-.5 x-3*-.5=3 x+1.5=3 x=1.5
