Add the square of half the x-coefficient to complete the square.
(-3/2)² = 9/4 = 2.25
Answer: -3
Step-by-step explanation:

We can check our work my multiplying -3 by -9 and see that it equals 27
![-9*[\frac{27}{-9} = -3 ]* -9\\27 = 27](https://tex.z-dn.net/?f=-9%2A%5B%5Cfrac%7B27%7D%7B-9%7D%20%20%3D%20-3%20%5D%2A%20-9%5C%5C27%20%3D%2027)
0.25x + 0.10y = 0.15*15
X + Y = 15
Y = 15 - X
0.25X + 0.10(15 - X) = 2.25
0.25X + 1.5 - 0.10X = 2.25
.15X = 0.75
X = 5
Y = 15 - 5
Y = 10
