Si compras 8 camisas más x pantalones, y compraste en total 13 articulos. ¿Qué ecuación describe el problema? ¿ Cuántos pantalones compraste en total?

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
