The missing score is a 79%.
Treat this equation like an average, and solve for x.
Well if you make them both equal to y I got...
Y=-3x+1
Y=5x-3
But I don't think you can find it without the y since they are different variables. Like I know -3x and 5x are the slopes and 1 and -3 are the y intercepts but I'm stuck after that. Sorry if that wasn't any help.
Hope I helped.
