Question

I'm having trouble answering this Simplifying Variable Expressions question I will have two pictures. One will be for the actual question and the other one is for the steps

Answer 1

Given the expression:

`-7(-15w+21)+3(18-27w)`

We will simplify the expression as follows:

1) using the distributive property to expand the expression:

`(-7)\cdot(-15w)+(-7)\cdot21+3\cdot18+3\cdot(-27w)`

2) using the commutative property:

`\begin{gathered} 105w-147+54-81w \\ =105w-81w-147+54 \end{gathered}`

3) Combine the like terms:

`=24w-93`

So, the answer will be 24w - 93
