Question

8+4*[3+3*(16+4*X:2+2):6]:31=12
Sa se afle X!!

Answer 1

8+4×[3+3×(16+4×X:2+2):6]:31 = 12
4×[3+3×(16+4×X:2+2):6]:31 = 12-8
4×[3+3×(16+4×X:2+2):6] = 4×31
3+3×(16+4×X:2+2):6 = 124:4
3×(16+4×X:2+2):6 = 31-3
3×(16+4×X:2+2) = 28×6
16 + 4 × X : 2 + 2 = 168:3
16 + 4 × X : 2 + 2 = 56
4 × X : 2 = 56-18
4 × X : 2 = 38
4 × X = 38×2
4 × X = 76 | :4
X = 19
