Answer:
(-1, 4)
Step-by-step explanation:
11x+5y=9
11x+3y=1
subtract side-by-side
- 5y-3y= 9-1
- 2y=8
- y=4
- 11x+20=9
- 11x= -11
- x=-1
The answer I got was 21 because 6x3=18 5x2=10 3-4=-1 and -1x3=-3
-3 x 2=-6 and the +2 so you would have
18+10+-3+-6+2
28+. -3+-6+2
25+-6+2
19+2
21
Answer: Weight of Charles = 177.5 pounds
Weight of dos = 22.5 pounds.
Step-by-step explanation:
Let x = Weight of Charles
y = Weight of dog.
As per given , we have the following system of linear equation :
We can write (ii) as :
Subtract equation (iii) from (i) , we get
Put this value in (1) , we get
Hence , Weight of Charles = 177.5 pounds
Weight of dos = 22.5 pounds.
