  1. \(3(8a-4)+6a=24a-12+6a=30a-12\).
  2. \(11c+5(8-c)=11c+40-5c=6c+40\).
  3. \(2(y-1)-2y+12=2y-2-2y+12=10\).
  4. \(16+3(2-3y)+8y=16+6-9y+8y=22-y\).
  5. \(7p-2(3p-1)=7p-6p+2=p+2\).
  6. \(3-17a-11(2a-3)=3-17a-22a+33=36-39a\).
  7. \(-4(3a+2)+8=-12a-8+8=-12a\).
  8. \(15-5(1-a)-6a=15-5+5a-6a=10-a\).
