R = recycling and reuse industry jobs
w = waste management jobs
we know, those two jobs combined are 1,275,000
or
r + w = 1,275,000
we also know that, whatever the "w" jobs are, are really less than "r"
jobs by 1,025,000
"r" has 1,025,000 more than "w"
or
r = w + 1,025,000
or
r-w = 1,025,000
so... there, just solve by elimination, simple, notice the "w",
is just waiting to be eliminated :)
