Question

Subtract –3(4x – 1) from 4(5x + 7).

Answer 1

`4(5x+7)--3(4x-1)=32x+25`

Step-by-step explanation

Note that the expression which comes immediately after from comes first.

`4(5x+7)--3(4x-1)`

We convert the minus minus to plus

`4(5x+7)--3(4x-1)=4(5x+7)+3(4x-1)`

We expand to obtain,

`4(5x+7)--3(4x-1)=20x+28+12x-3)`

We group like terms to obtain,

`4(5x+7)--3(4x-1)=20x+12x+28-3`

We simplify to obtain,

`4(5x+7)--3(4x-1)=32x+25`
