2a%2B6=-a-8 Start with the given equation.


2a=-a-8-6 Subtract 6 from both sides.


2a%2Ba=-8-6 Add a to both sides.


3a=-8-6 Combine like terms on the left side.


3a=-14 Combine like terms on the right side.


a=%28-14%29%2F%283%29 Divide both sides by 3 to isolate a.

Answer:

So the solution is a=-14%2F3

2a+6=-a-8
-----
Add a to both sides to get:
3a + 6 = -8
Subtract 6 from both sides to get:
3a = -14
----
Divide both sides by 3 to get:
a = -14/3

2a+6=-a-8
You find that the variable a is on both sides of the = sign.
to find the value of a you have to have the a's on one side and the numbers on the other side.
Fisrt lets bring the a on the right side to the left of the = sign
add a to both sides of the equation
2a+a+6 =-a+a-8
2a+a=3a, +a & -a= 0 on the right side. You have -8 left
3a+6 =-8
we remove the number from the left side of the = sign
add -6 to both sides of the equation
3a+6-6 = -8-6
+6 & -6 =0
3a= -14
Now the 3 has to be eliminated to find the value of a
you divide both sides of the equation by 3
%28cross%283%29%29a%2F%28cross%283%29%29 =+-14%2F3
a=-14%2F3
