Answer 1

Răspuns:

3 + 222 : 2 x 5 + [92 + 2 x 4 x (29 - a x 2 : 7) x 9] + 100 = 2 550​

3 + 111 x 5 + [92 + 2 x 4 x (29 - a x 2 : 7) x 9]  = 2 550​ - 100

3 + 555 + [92 + 2 x 4 x (29 - a x 2 : 7) x 9] = 2450

92 + 2 x 4 x (29 - a x 2 : 7) x 9 = 2450 - 555 - 3

92 + 2 x 4 x (29 - a x 2 : 7) x 9 = 1892

2 x 4 x (29 - a x 2 : 7) x 9 = 1892 - 92

8 x (29 - a x 2 : 7) x 9 = 1800

(29 - a x 2 : 7) x 9 = 1800 / 8

(29 - a x 2 : 7) x 9 = 225

29 - a x 2 : 7 = 225 / 9

29 - a x 2 : 7 = 25

a x 2 : 7 = 29 - 25

a x 2 : 7 = 4

a x 2 = 7 * 4

a x 2 = 28

a = 28 / 2

a = 14
