The answer is 56 percent black pens
Answer:
-4u -5v
Step-by-step explanation:
Let the sum be ...
<3, -27> = a<3, 3> +b<-3, 3>
This resolves to two equations
3 = 3a -3b
-27 = 3a +3b
Adding these together, we get
-24 = 6a
a = -4
Substituting into the second equation gives ...
-27 = 3(-4) +3b
-15 = 3b
-5 = b
The desired linear combination is ...
<3, -27> = -4<3, 3> -5<-3, 3> = -4u -5v
