Question

Aflatil pe a din{176x12+(123:3+a)+98]=124

Answer 1

{2112+(41+a)+98=124
2112+(41+a)=124-98
2112+(41+a)=26
41+a=2112-26
41+a=2086
a=2086-41
a=2127
V:41+2127=2086

Answer 2

[176x12+(123:3+a)+98]=124
[2112+(41+a)+98]=124
2112+(41+a)=124-98
2112+(41+a)=26
41+a=26-2112
41+a= -2086
a= -2086-41
a= -2127
