Does anyone know how to do this HELP

Answer 1

-1.5(4-n)+2.8-1.5(4-n)+2.8


-3/2x(4-n)+2.8-1.5(4-n)+2.8
-3/2x(4-n)+14/5-1.5(4-n)+2.8
-3/2x(4-n)+14/5-3/2x(4-n)+2.8
-3/2x(4-n)+14/5-3/2x(4-n)+2.8



-1/10x(15(4-n)-28+15(4-n)-28)


-1/10x(60-15n-28+15(4-n)-28)
-1/10x(60-15n-28+60-15n-28)

-1/10x(64-15n-15n)
-1/10x(64-30n)

-1/10x2(32-15n)

-1/5x(32-15n

Answer 2

`3n-6.4`

Explanation:

`-1.5(4-n)+2.8-1.5(4-n)+2.8`

Collect like terms:

`(-1.5(4-n)-1.5(4-n))+(2.8+2.8)`

Simplify:

`-3(4-n)+5.6`

Expand:

`-12+3n+5.6`

Collect like terms:

`3n+(-12+5.6)`

Simplify:

`3n-6.4`
