Question

What is the simplfied form of (4r-s)-(r+2s)-(5r-3s)

Answer 1

-2r

Step-by-step explanation

We want to find the simplified form of:

`\mleft(4r-s\mright)-\mleft(r+2s\mright)-\mleft(5r-3s\mright)​`

To do this, we have to expand each bracket and then, simplify by collecting like terms:

`\begin{gathered} 4r-s-r-2s-5r+3s \\ 4r-r-5r-s-2s+3s \\ -2r-3s+3s \\ -2r \end{gathered}`

That is the simplified form.
