Please help and show work!!

Answer 1

we are given

`y-7=-(x+1)`

Firstly, we will distribute negative sign on right side

`y-7=-x-1`

Since, we have to move both x and y on anyone side

so, we will add x on both sides

`y-7+x=-x-1+x`

`y-7+x=-1`

now, we add 7 on both sides

`y-7+x+7=-1+7`

`y+x=6`

`x+y=6`.................Answer
