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
=
