Why is

[tex]9y + 7 = 2y + 98[/tex]

The relationship between 9y + 7 and 2y + 98 is that both angles are vertically opposite

In geometry, vertically opposite angels are equal

In other words, if a and b are vertically opposite angles, then a = b

So, we can say that:

[tex]9y + 7 = 2y + 98[/tex]

because they are vertically opposite
