Question

1+2×{3+4×[5+6×(7+8×y)]}=3839

Answer 1

2*{3+4*[5+6*(7+8*y)]}=3838
3+4*[5+6*(7+8*y)]=3838:2=1919
4*[5+6*(7+8*y)]=1919-3=1916
5+6*(7+8*y)=1916:4=479
6*(7+8*y)=479-5=474
7+8*y=474:6=79
8*y=79-7=72
y=72:8
y=9

Imi dai coronita te rog frumos?

Answer 2

REZOLVARE:
2*{3+4*[5+6*(7+8*y)]}=3839|-1
=3838
{3+4*[5+6*(7+8*y)]}=3838|:2
=1919
4*[5+6*(7+8*y)]}=1919|-3
=1916
[5+6*(7+8*y)]}=1916|:4
=479
6*(7+8*y)=479|-5
=474
7+8*y=474|:6
=79
8*y=79|-7
8*y=72
y=72:8
y=9
