Află valoarea fiecărei litere: 194 x 3 + 200 - a = 493; (104 x 4 + 83 x 5) - ax 3 = 8 x 100 + 36:9; (138 x 5 - 21:7 - 300 x 2) – 9x9-rx 2 = 2.
40:8 + 124 x 5 + i = 719; (321 x 2 - 115 x 4) + 42:1 = 180 + 2 x 4;

Explicație pas cu pas:
1) 194 x 3 + 200 - a = 493
582 + 200 - A = 493
782 - A = 493
A = 782 - 493
A = 289
V : 194 x 3 + 200 - 289 = 493
2) (104 x 4 + 83 x 5) - A x 3 = 8 x 100 + 36 : 9
(416 + 415) - A x 3 = 8 x 100 + 36 : 9
831 - A x 3 = 800 + 4
831 - A x 3 = 804
A x 3 = 831 - 804
A x 3 = 27
A = 27 : 3
A = 9
V : (104 x 4 + 83 x 5) - A x 3 = 8 x 100 + 30 : 9 = 804
8 x 100 + 36 : 9 = 804
----------------------------------
3) (138 x 5 - 21 : 7 - 300 x 2) - 9 x 9 - R x 2 = 2
(915 - 3 - 600) - 9 x 9 - R x 2 = 2
312 - 9 x 9 - R x 2 = 2
312 - 81 - R x 2 = 2
231 - R x 2 = 2
462 - R = 2
R = 462 - 2
R = 460
V : 460 - 460 = 2
4) 40 : 8 + 124 x 5 + i = 719
5 + 620 + i = 729
625 + i = 729
i = 729 - 625
i = 104
5) (321 x 2 - 115 x 4 ) + 42 : 1 = 180 + 2 x 4
(321 x 2 - 115 x 4 ) + 42 : 1 =180+8 = 188
(642- 460 ) + 42 : 1 = 188
182 + 42 : 1 = 188
182 + 42 = 224
224 = 188
