During one week the company used 290 sq.ft of leather to make 40 pairs of size 10 men's hiking boots and 60 pairs of size 7 women's hiking boots. Another week the company used 275 sq. ft of leather to make 50 pairs of size 10 men's hiking boots and 40 pairs of size 7 women's hiking boots.
a) How much leather is used to make one pair of size 10 men's hiking boots?
b) How much leather is used to make 1 pair of size 7 women's hiking boots?

Our teacher wants us to set up two equations for each problem, and solve them with substitution or elmination. This is what I have tried so far:
x - mens
y - womens
40x + 60y = 290
50x + 40y = 275

Am I on the right track?
