We have 3X+4Y = 16 (1)\nY - 3X = 11 (2)\n\nAdding (1) and (2)\n\nY + 4Y = 27\n\nor\n\n5Y = 27 --> Y = 27/5 = 5 + 2/5 = 5.4\n\nreplacing in (2)\n\n27/5 - 3X = 11\n\ntherefore\n\nX = (11-5.4)/(-3) = -5.6/3

4x +y = 16   ;2x + 3y = 24      Multiply the 2nd with -2, that gives -4x -6y = -48    Add the two:   0x - 5y = -32  \nDivision by -5 gives  y = 6,4\nInsert this value into the first equation:   4x + 6,4 = 16\n4x = 9,6 ;    x = 2,4\n\nNumber 2 is even easier:\nMultiply the first equation by 2 and add the equations.\n24x + 2y = 50    plus   8x - 2y = 14  gives  32x = 64; x = 2\nYou can now choose:  24 + y = 25  or  16 - 2y = 14\n(That you get when you replace in the original equations \nx by 2)  Anyhow you'll find   y = 1
