let a = k3 , b = k5 , c = k7.50
b = 3 a
c = b + 500
3 a + 5 b + 7.5 c = 42225
substituting ... 3(b / 3) + 5 b + 7.5(b + 500) = 42225
solve for b , then substitute back to find a and c
b = 3 a
c = b + 500
3 a + 5 b + 7.5 c = 42225
substituting ... 3(b / 3) + 5 b + 7.5(b + 500) = 42225
solve for b , then substitute back to find a and c
