Answer:
37
Step-by-step explanation:
Stare at if for a while and try to find a pattern. Every time you increase x by 1, y increases by 3, so it's linear. Since at [tex]x=0 \rightarrow y=-3[/tex] I would assume it's
[tex]y=3x-3[/tex] (3 as a slope is the y variation for unit increase in x, and -3 is simply the value at 0). If you keep looking at the values give all fit the model, so we're good here. Let's plug y=108:
[tex]108= 3x-3 \rightarrow 36=x-1 \rightarrow x=37[/tex]
