Answer: Se colocará 220 peces en cada pecera pero necesitaremos 1 pecera más para colocar los 7 peces restantes.
Step-by-step explanation:
4627/21=220.33....
21*220=4620
4627-4620=7 peces restantes en la última pecera
Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x
-5x-7= 3
+7. +7
-5x= 10
Divide -5 on both sides and you get x= -2
Then substitute -2 in the first equation
-2(-2)-7
4-7
Y= -3
