Question

Se tiene que P(2x-3) = 3x+5

Hallar T=P(P(3)-6)

Answer 1

Respuesta:

T = 21.5

Explicación paso a paso:

• 2x - 3 = 3

x = 3

P(3) = 3(3) + 5 = 14

• P(3) - 6 = 14 - 6 = 8

• 2x - 3 = 8

x = 11/2

P(8) = 3(11/2) + 5 = 16.5 + 5 = 21.5

O también...

P(2x - 3) = (3x + 5)... (×2/3)

(2/3) P(2x - 3) = 2x + 10/3 - 3 + 3

(2/3) P(y) = y + 19/3

P(x) = 3x/2 + 19/2 = (3x + 19) ÷ 2

P(x) = 3x + 19

P(x) = 3x + 19 2

P(3) = 14

T = P(P(3) - 6) = P(14 - 6) = P(8) = 21.5
