Answer:
x= -11;y= -19
Step-by-step explanation:
lets name y-2x=3 "A" ;
name 3x-2y=5 "B".
2A: 2y-4x=6
2A+B: (2y-4x)+(3x-2y)=6+5
2y-4x+3x-2y=11
-x=11
so x= -11
so A is : y-2 (-11)=3
y+22=3
so
y= -19
Answer:
2z2(2y - 5) = 4z2y - 10z2

Answer: Permutation is involved , since order of prizes matters.
The number of different ways the prizes can be awarded =95060
Step-by-step explanation:
Given : Total number of people purchase lottery tickets =100
The number of prizes = 3
Since each prize can be claimed by only one person.
So order matters here, there for we use permutations .
The number of permutations of n objects taken m at a time is given by :-

Then, the number of different ways the prizes can be awarded :-
