Answer:
Simplifying
8a + -6 + a + -1 = 0
Reorder the terms:
-6 + -1 + 8a + a = 0
Combine like terms: -6 + -1 = -7
-7 + 8a + a = 0
Combine like terms: 8a + a = 9a
-7 + 9a = 0
Solving
-7 + 9a = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + 9a = 0 + 7
Combine like terms: -7 + 7 = 0
0 + 9a = 0 + 7
9a = 0 + 7
Combine like terms: 0 + 7 = 7
9a = 7
Divide each side by '9'.
a = 0.7777777778
Simplifying
a = 0.7777777778
