a) El numero borrado es 2.
b) El numero borrado es 1.
Explicación paso a paso:
a)
[tex]\frac{4}{5}[/tex] + [tex]\frac{x}{15}[/tex] + = [tex]\frac{14}{15}[/tex]
12 + x = 14
x = 14 - 12
x = 2
b)
[tex]\frac{x}{3}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{11}{15}[/tex]
5x + 6 = 11
5x = 11 - 6
5x = 5
x = 1
