Jake Posted June 16, 2008 Share Posted June 16, 2008 X2 - 2Y = 20 X + Y = 5 Whats the value of X and Y? X2 being X Squared x = 4.56776436283002 y = 0.43223563716998 ------------------------------------------------- 4.56776436283002 + 0.43223563716998 = 5.0 (X squared) ... 4.56776436283002² = 20.8644712743399 (2*Y) ... 0.43223563716998 *2 = 0.864471274339961 (X squared) minus (2*Y) ... 20.8644712743399 minus 0.864471274339961 = 20.0 Link to comment Share on other sites More sharing options...
