Draw The Graph Of Each Of The Following Linear Equations In Two Variables I X Y 4 Ii X Y Youtube
You just studied 10 terms! x − y = 2 −−−−−−−−− ← add to and up with only 1 unknown 2x 0 = 8 Divide both sides by 2 Thus x = 4 '~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To determine value of y Substitute x = 4 into x y = 6 giving x y = 6 → 4 y = 6 Subtract 4 from both sides
