Simplify each expression
4+8(-2n+3)

  28 -16n

Step-by-step explanation:

Use the distributive property, then collect terms.

  4 +8(-2n +3)

  = 4 +8(-2n) +8(3)

  = 4 -16n +24

  = 28 -16n

This could also be written

  -16n +28

but then the leading sign would be negative. Sometimes leading minus signs get lost, so I prefer the first term to be positive.
