das y del otro sabor 10. Si al final se contaron 800 rebanadas,
¿cuántos pasteles de cada tipo donó la pastelería?​

Answer 1

Answer: 40 one flavor cakes and 60 other favor of cakes

Step-by-step explanation:

Let x = Number of one flavor of cakes

y = Number of other flavor of cakes

According to the question

$x+y=100...(i)\\5x+10y= 800...(ii)$

Divide (ii) by 5 , we get

$x+2y= 160...(iii)$

Eliminate (i) from (iii), we get

$y=60$

Put this in (i), we get

$x+60=100\Rightarrow\ x=40$

Hence, 40 one flavor cakes and 60 other favor of cakes were donated.
