Your equations are right. just use the substitution method to solve. substitute y because both have that on one side
it'll look like 40x+30=30x+60.
then just get x in one side. I showed my owrk in the photo

Answer:
3.47 and 3.21
Step-by-step explanation:
Let us assume the nails length be X
Value let separated the top 3% is T and for bottom it would be B
Now converting, we get
Based on the normal standard tables, we get
Now compare these two above equations
So for top 3% it is 3.47
Now for bottom we applied the same method as shown above
Based on the normal standard tables, we get
Now compare these two above equations
hence, for bottom it would be 3.21
