Answer:
500 de no ficcion y 1500 de ficcion
Step-by-step explanation:
si tomamos que hay 2000 libros hay que buscar un numero que multiplicado 3 veces por si mismo nos de 2000, como ya tenemos el 500 que seria los libros de no ficcion, ahora tenemos que e si al multiplicarlo por 3 veces nos da los 1500 que nos falta para completar 2000

Answer:
e = 9
Step-by-step explanation:
ok e is just x, so we have to get it alone
4e - 10 = 2e + 8
We move the 2 since its smaller than the 4, and we move it two the other side. 4-2=2 so the new e is 2, now that 8 is alone (since we moved the 2), we cant be having the e with the -10... like this..
2e - 10 = 8, so we now add 10 so it can go with the 8, the new equation is this..
2e = 18
18/2 = 9
simple explanation
4e - 10 = 2e + 8
2e = 18
e = 9
(does that make sense)
9x4=? Because there are 4 groups of 9 so it is multiplication.<span />
