3,45 – 2,5 + x = 1,78                        x + (9,7 – 5,54) = 61,2

0,95 + X = 1,78                                X + 4,16 = 61,2

           X = 1,78 - 0,95                      X            = 61,2 - 4,16

           X = 0,83                                X            = 57,04

12,3 – x + 4,5 = 2,3                           (x + 37,6) – 20,8 = 21,7

X + 4,5 = 12,3 - 2,3                             X - 20,8 = 21,7 + 37,6

X + 4,5 = 10                                        X - 20,8 = 59,3

X          = 10 - 4,5                                X           = 59,3 + 20,8

X          = 5,5                                       X           = 80,1
