Answer:
Takeru bought 72 eggs and baked 18 soufflés .
Step-by-step explanation:
Let
e = number of eggs Takeru bought.
s = number of soufflés Takeru bought.
Then we know that Takeru bought 4 times as many eggs as he baked soufflés, therefore:
![e=4s.](https://tex.z-dn.net/?f=e%3D4s.)
And since for every soufflés Takeru bakes he uses 3 eggs, and after backing he has 18 eggs left, we have:
<em>This says that from
eggs there are 18 eggs left after Tkeru used three eggs for each soufflé.</em>
Now we have two equations:
![(1).e=4s.](https://tex.z-dn.net/?f=%281%29.e%3D4s.)
![(2).e-3s=18](https://tex.z-dn.net/?f=%282%29.e-3s%3D18)
We put the value of e from equation (1) into equation (2) and solve for s and get:
![s=18](https://tex.z-dn.net/?f=s%3D18)
![e=4s=4*18=72.](https://tex.z-dn.net/?f=e%3D4s%3D4%2A18%3D72.)
Thus
Number of eggs Takeru bought = 72.
Number of soufflés Takeru bought = 18.
