Last year's salary is $32000
Step-by-step explanation:
We will use the linear equations to solve the given problem
Let x be the last years salary
then
0.06x will be the raise in the salary
This year's salary is $33920
So,
![x+0.06x=33920\\1.06x=33920](https://tex.z-dn.net/?f=x%2B0.06x%3D33920%5C%5C1.06x%3D33920)
Dividing both sides by 1.06
![\frac{1.06x}{1.06}=\frac{33920}{1.06}\\=32000](https://tex.z-dn.net/?f=%5Cfrac%7B1.06x%7D%7B1.06%7D%3D%5Cfrac%7B33920%7D%7B1.06%7D%5C%5C%3D32000)
Hence,
Last year's salary is $32000
