Variantele: a=32 b=34 c=36
Dau coroana si multe puncte

Answer 1

[936-(8×100+a)]:[10+(35:5+8)]=4
[936-(8x100+a)]:[10+(7+8)] =4
[936-(800 + a)] : [10 + 15] = 4 
[936-(800 + a)] : 25 = 4 
936 - (800 + a) = 4 x 25 
936 - (800 + a) = 100 
800 + a = 936 - 100
800 + a = 836 
a = 836 - 800
a = 36 ( c ) 

Answer 2

[936 - (8 * 100 + a)] : [10 + (35 : 5 + 8)] = 4
[936 - (800 + a)] : [10 + 15] = 4
936 - 800 - a = 4 * 25
- 800 - a = 100 - 936
- a = - 836 + 800
a = 36
R. c) 36
