There are no solutions I can find. Mabye there are no solutions.
Sorry that I'm dumb- ;-;
The answer is b :) have a good day
-10y + 9x = - 9....A
10y + 5x = - 5.....B
You should see right away that -10y and 10y cancel out.
We are left with
14x = -14
x = -14/14
x = -1
Plug x = -1 into EITHER equation A or B to find y.
I will use equation A.
-10y + 9(-1) = - 9
-10y - 9 = - 9
-10y = - 9 + 9
- 10y = 0
y = 0/-10
y = 0
Done!
1 kg = 0.001 metric tons..so 14327 kg = (14327 * 0.001) = 14.327 metric tons
and if 1 metric tons saves 17 trees....then 14.327 tons saves : 14.327 * 17 = 243.559 saved trees...and since u cant have 0.559 trees, u would round to 243 trees
