Sejam (1) = 4 e ( + 1) = 3 ⋅ () − 2 funções do primeiro grau com domínio no conjunto dos números naturais. Nessas condições, qual o valor de (0)? f(0) = b f(1) = a + b = 4 f(x + 1) = ax + 4 3ax + 3b - 2 = ax + 4 3ax + 3b = ax + 6 não sei como continuar, alguem ajuda?

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?
