Respuesta :

Let's begin by listing out the information given to us:

[tex]\mleft(8x+1\mright)+\mleft(-9x+7\mright)[/tex]

We will open the bracket, we have:

[tex]8x+1-9x+7[/tex]

Put like terms together, we have:

[tex]\begin{gathered} 8x-9x+1+7 \\ \Rightarrow-x+8 \end{gathered}[/tex]

Therefore, (8x + 1) + (-9x + 7) = -x + 8
