Expressions that are equivalent to 9x + 7x + 8 - 7x - 9.

Answer 1

`\text{Hey there!}`

`\mathsf{9x+7x+8-7x-9}`

`\mathsf{Combine\ your\ like\ terms}`

`\mathsf{Like\ terms \ \#1: 9x,7x, \ \& \ -7x}`

`\mathsf{Like\ terms\ \#2: 8\ \& \ -9}`

`\mathsf{(9x+7x-7)+(8-9)}`

`\mathsf{Now\ solve!}`

`\mathsf{9x+7x-7x}\\\mathsf{9x+7x=16x}\\\mathsf{16x-7x=9x}\\\mathsf{\underline{=9x}}`
`\leftarrow\mathsf{left\ value}`

`\mathsf{8-9=-1}\\\mathsf{\underline{=-1}}`
`\leftarrow{\mathsf{right\ value}}`

`\mathsf{Finally\ we\ have\ the\ answer\ to\ your\ question!}`

`\boxed{\boxed{\huge\text{\bf{Answer:9x - 1}}}}\checkmark`

`\text{Good luck on your assignment and enjoy your day!}`
