Answer:
y=-5/2+x
Step-by-step explanation:
You need to solve a system comprised of 3 equations.
1) k+m+n=1500
2) m=3n
3) k=2n
Replace equations 2) and 3) in 1) => 2n+3n+n=1500 => 6n=1500 => n=250
By reaplacing n in 2) => m=3*250=750
In 3) => k=2*250=500
2d = 5c
2/5 = c/d ...true
5/2 = d/c...true
2/c = 5/d...true
2/d = 5/c....not true
