Explicație pas cu pas:
x + 5*161 = 895
x + 805 = 895
x = 895 - 805 = 90
_____________
x - 53*(49 - 36) = 996
x - 53*13 = 996
x - 689 = 996
x = 996 + 689 = 1685
______________
53 + 2A = A + 111
2A - A = 111 - 53
A = 58
______________
23 + 5D = 2*? + 74 ecuatia este incompleta; presupun ca era 2*D
23 + 5D = 2D + 74
5D - 2D = 74 - 23
3D = 51
D = 51 : 3 = 17
_____________
32 + 6c = 11c - 113
11c - 6c = 32 + 113
5c = 145
c = 145 : 5 = 29
__________________
8 + 13a = 2a + 41
13a - 2a = 41 - 8
11a = 33
a = 33 : 11 = 3
Răspuns:
x+5·161=895
x+805=895
x=895-805=90
_____________
x-53(49-36)=996
x-53·13=996
x-689=996
x=996+689
x=1685
______________
53+2A=A+111
2A-A=111-53
A = 58
______________
32+6c=11c-113
11c-6c=32+113
5c=145
c=145:5
c=29
