Answer & Explanation
ANS: 28
EQ 1=> X + X = 22 => 2X = 22 => X = 11
EQ 2=> Y × X = 77 => Y × 11 = 77 => Y = 7
EQ 3=> 2Z × Y = 84 => 2Z × 7 = 84 => 2Z = 12 => Z = 6
EQ 4=> Z + 2X => 6 + 2(11) => 28
EQ 1=> X + X = 22 => 2X = 22 => X = 11
EQ 2=> Y × X = 77 => Y × 11 = 77 => Y = 7
EQ 3=> 2Z × Y = 84 => 2Z × 7 = 84 => 2Z = 12 => Z = 6
EQ 4=> Z + 2X => 6 + 2(11) => 28
