So According to this equation 2x + 5 = -1 => 2x = -1-5 (As when 5 goes to the right side so it sign changes) => 2x = -6 => x = -6/2 (as when 2 goes to the right side it gets divided) *Ans = x=-3* Hope it helps you!
Restaurant D offered the best deal at $13.05 per 9 shrimp because it you but 18 it will only cost you 26.15 but if you buy from restaurant A you only get 16 shrimp for 26.40 so I'd say go wit restaurant D
