x=0 and y=
Step-by-step explanation:
We need to solve the system by elimination and find values of x and y
Subtract eq(1) and eq(2)
Now Multiply equation (1) by 2 and subtract with eq(2)
So, x=0 and y=

Answer:
The correct answer is 34 people
Step-by-step explanation:
Killing 3 people does not change the number of people in the bedroom, it only means that there are 30 dead people and 4 living people, but overall, here are 34 people in the room.
To solve this we will use inverse operations.
The inverse operations for subtraction is addition.
y - 10 = 32
32 + 10 = 42
So, y = 42 BUT lets check our work.
42 - 10 = 32.
So y = 42.
Answer:
9.49525
Step-by-step explanation:
You have the total and the percent so you are looking for the part. You can set up a proportion with 9.5 over 100 and x over 99.95. Then you multiply 9.5 times 99.95 to get 949.525 which then you divide by 100. So x is 9.49525
