Answer:
C) never
Step-by-step explanation:
It means the system of equations is true for all values of the variables that satisfy one of the equations. The other equation is identical, so any values that satisfy the first equation will also satisfy the second equation.
There will be an infinite number of solutions. There will never be no solution.

<u>Example</u>:
x + y = 4
-x -y +4 = 0
Adding the two equations gives ...
(x +y) +(-x -y +4) = (4) + (0)
4 = 4
The solutions to this system are all values of x and y such that x+y=4. There are an infinite number of such solutions.

Answer:
a=4
Step-by-step explanation:
<u>Question: 4-8a=4(5-3a)</u>
<u />
1) Distribute 4 to 5 and -3a:
4-8a=20-12a
2) Add 12a to both sides:
4+4a=20
3) Subtract 4 from both sides:
4a=16
4) Divide both sides by 4:
a=4
Footnotes:
- The <em>Distributive</em> property says a(b+c)=ab+ac
It would be the first one because it’s going up by a constant rate
