The numbers are "a" and "b"
so we know a*b = 280 and a+b = -34
well
solve for "a"
what's b? well, b = 280/a
so we know a*b = 280 and a+b = -34
well
solve for "a"
what's b? well, b = 280/a
It's geometry, not really sure what to do

ANSWER
Find out the how many pounds of nickel have to be used to create alloy that contains 4.9 lb of zinc.
To proof
As given
An alloy consists of nickel, zinc, and copper in the ratio 2:7:9.
the total part of the alloy are 18.
assuming one part be x.
thus
nickel part = 2x
zinc part = 7x
copper part = 9x
alloy that contains 4.9 lb of zinc.
than the equation becomes
7x = 4.9
x = 0.7
Therefore
nickel part = 2x
= 2× 0.7
= 1.4 lb
1.4 lb of nickel have to be used to create alloy that contains 4.9 lb of zinc.
Hence proved
