Step-by-step explanation:
Multiply the first equation by 3
21x+15y=-6
Add this to the second equation
21x+15y=-6
-21x-15y=6
0+0=0
True

Answer:
The simplified expression would be: -6.3n + 8.6
Step-by-step explanation:
First is to write out the expression:
3.6 - 4.3n - 2n + 5
Then re-sort the expression:
-4.3n - 2n + 5 + 3.6
-4.3n - 2n = -6.3n
5 + 3.6 = 8.6
Your final expression would be:
- 6.3n + 8.6
