Question

Which expression is equivalent to (–3y – x) – (5y – 8x)?

Answer 1

I hope this helps.

-8y+7x

Answer 2

`7x-8y`

Explanation:

We have been given an expression
`(-3y-x)-(5y-8x)`. We are supposed to simplify our given expression.

Using distributive property
`a(b+c)=ab+ac`, we will get:

`-3y-x-1*5y-1*-8x`

`-3y-x-5y+8x`

Now, let us combine like terms.

`-x+8x-5y-3y`

`7x-8y`

Therefore, the simplified form of our given expression would be
`7x-8y`.
