Answer:

Queremos hacer un problema donde tengamos adición (a + b) y substracción ( a - b) de números con signo, de tal forma que el resultado final sea 9.

El caso más simple para este tipo de problemas es algo como:

"Vas a un mercado a comprar un par de productos, el producto A cuesta $A, y el producto B cuesta $B, si solo tenés un billete de $C, cuanto será el vuelto?"

Bueno, el vuelto va a ser la diferencia entre lo que vos entregáis, $C, y el costo total de los productos que compras ($A + $B)

Entonces el vuelto va a ser:

vuelto = $C - ($A + $B)

Y queremos que el resultado de este problema sea 9, entonces podemos escribir:

vuelto = $9 = $C - ($A + $B)

Ahora debemos encontrar los valores de las incógnitas.

Podemos simplemente definir dos de ellas y encontrar la tercera, por ejemplo si $C = $20 y $A = $2, entonces:

$9 = $20 - ($2 + $B)

$9 = $20 - $2 -$B

$9 = $18 - $B

$9 - $18 = -$B

-$9 = -$B

Entonces $B será = $9.

Y el problema podría escribirse como:

"Vas a un mercado a comprar un par de productos, el producto A cuesta $2, y el producto B cuesta $9, si solo tenés un billete de $20, cuanto será el vuelto?"

4p = 2p + 3c....p = popcorn, c = candy bars

4p - 2p = 18
2p = 18
p = 18/2
p = 9......whoa....9 bucks for popcorn....nothing is cheap anymore

F(4) is equivalent to 28 because when you plug in 4 for the x, you get 28.
