I know a can be equal to 1.

nv, i got it, the answer is 8.

Invertible, meaning it has an multiplicative inverse.

"Modulo m graph paper" consists of a grid of m^2 points, representing all pairs of integer residues (x,y) where 0=<x=<m. To graph a congruence on modulo m graph paper, we mark every point (x,y) that satisfies the congruence. For example, a graph of ywould consist of the points (0,0),(1,1) ,(2,4) ,(3,4) , and (4,1).

The graph of  has a single x-intercept $(x_0,0)$ and a single y-intercept $(0,y_0)$, where $0\le x_0,y_0<35$.

What is the value of $x_0+y_0$?

Sorry, too lazy for LaTeX now, 

But....help? I don't understand. :(

I don't know how. :(

And this, too.

HELP!!!
