Answer:
5x - 2y = - 2
Step-by-step explanation:
Given the 2 equations
- 2x + y = 0 → (1)
- 7x + 3y = 2 → (2)
Subtracting (2) from (1) term by term
- 2x - (- 7x) + y - 3y = 0 - 2, that is
- 2x + 7x - 2y = - 2
5x - 2y = - 2
After 2 hours of reading, you read 10 chapters (or pages) of a book. You could also say after 2 days, it snowed 10 inches.
First because 5x+5y=0 you can factor the 5
from equation so:
5(x+y) =5 (0) => x+y=0
and by solving for × using elimination method
-8x+y=36
x+y=0
by subtracting both x and y we get
-9x=36 => x=-4
by inputing × into the "x+y=0" equation so we get:
-4+y=0 => y=4
The answer is 56.
Firstly you have to multiply the 2 numbers together, which would be the places of b and h. This would give you 112.
Then, divide 112 by 2 to give you a final answer of 56.
