[(603 - 135:6 + 135:12:x ):4 -144]:10 = 1+ 1 (603:4 - 135:6 + 135:12:x):4:10 -144:10 = 2 Inmultim egalitatea cu 10: (603:4 - 135:6 +135:12:x):4 -144 = 20 Inmultim cu 4: 603:4 - 135:4 + 135:12:x -144*4 = 20*4 135:12:x = 20*4 + 144*4 - 603:4 + 135 :4 135:12:x = 164*4 - 468:4 = 164*4 - 117 135/(12:x) = 164*4 -117 135*x/12 = 164*4 - 117 x = (164*4 -117)*12/135 = (656 - 117)*12/135 = 539*12/135 = 47,91 x = 47,91
