Answer 2

Answer:

Simplifying

3 + 9a + -6a = 0

Combine like terms: 9a + -6a = 3a

3 + 3a = 0

Solving

3 + 3a = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 3a = 0 + -3

Combine like terms: 3 + -3 = 0

0 + 3a = 0 + -3

3a = 0 + -3

Combine like terms: 0 + -3 = -3

3a = -3

Divide each side by '3'.

a = -1

Simplifying

a = -1
