a. \(327 \times (126 + x) = 67035\)
\(126 + x = 67035 : 327\)
\(126 + x = 205\)
\(x=205-126=79\)
b. \(10208 : (108 + x) = 58\)
\(108 + x = 10208 : 58\)
\(108 + x = 176\)
\(x=176-108=68\)
c. \(68 \times (236 - x) = 9860\)
\(236 - x = 9860 : 68\)
\(236 - x = 145\)
\(x=236-145=91\)
d. \(17856 : (405 - x) = 48\)
\(405 - x = 17856 : 48\)
\(405 - x = 372\)
\(x=405-372=33\)
