Question

58296-198X7:[531:9-(5XYX2-248:8)-4×9]×588=84

Answer 1

58296-198×7:[531:9-(5×Y×2-248:8)-4×9]×588=84
58296-198×7:[59-(10Y-31)-36]×588=84
1386:[59-(10Y-31)-36]×588=58212
1386:[59-(10Y-31)-36]=58212:588
1386:[59-(10Y-31)-36]=99
[59-(10Y-31)-36]=1386:99
59-(10Y-31)-36=14
59-(10Y-31)=14+36
59-(10Y-31)=50
10Y-31=9
10Y=9+31
10Y=40
Y=40:10
Y=4
