Answer:
a - 8
Explanation:
7a−6+3−8a−(−2a+5)
Distribute the Negative Sign:
=7a−6+3−8a+−1(−2a+5)
=7a+−6+3+−8a+−1(−2a)+(−1)(5)
=7a+−6+3+−8a+2a+−5
Combine Like Terms:
=7a+−6+3+−8a+2a+−5
=(7a+−8a+2a)+(−6+3+−5)
=a + −8
Answer:
= a − 8
Answer:
No solution
Step-by-step explanation:
So the equation is saying that -3 is equal to 3. But that is false so it would make the system of linear equations be no solution. Which means that you are giving a number that is equal to another number when its not. For example, lets say that you are given 4=-20 well that would be no solution because those aren't equal. Now lets say you are given 20=20 that would be infinitely many solutions because the two numbers are equal to each other.

The lights cost 45 dollars per bulb and 6 go out per day, 45×6=270
