What is X plus 3y equals 2 and 2x - 3y equals 22?
Simple system. X + 3Y = 2 2X - 3Y = 22 ------------------------add 3X = 24 X = 8 --------------------now, insert back into one of the equations to find Y 8 + 3Y = 2 3Y = - 6 Y = - 2 ----------------check both equations 8 + 3(- 2) = 2 2 = 2 ---------------top checks 2(8) - 3(- 2) = 22 16 + 6 = 22 22 = 22 ----------------both are consistent, so X = 8 Y = - 2
