Answer 1

Răspuns:

8+4*{3+3*[X+4*(X:2+2)]:6}:31=12

4*{3+3*[X+4*(X:2+2)]:6}:31=12-8

4*{3+3*[X+4*(X:2+2)]:6}:31=4

4*{3+3*[X+4*(X:2+2)]:6}=4*31

4*{3+3*[X+4*(X:2+2)]:6}=124

3+3*[X+4*(X:2+2)]:6=124:4

3+3*[X+4*(X:2+2)]:6=31

3*[X+4*(X:2+2)]:6=31-3

3*[X+4*(X:2+2)]:6=28

3*[X+4*(X:2+2)]=28*6

3*[X+4*(X:2+2)]=168

X+4*(X:2+2)=168:3

X+4*(X:2+2)=56

X+4*(X:2)+4*2=56

X+2*X+8=56

3*X=56-8

3*x=48

x=48:3

x=16
