First, distribute the numbers outside of the parentheses:
2(3a) + 2(9) = -0.5(-2a) + (-0.5)(6)
Simplify the equation further:
6a + 18 = 1a - 3
Next, move all the variables to one side and the constant numbers to the other side:
6a - 1a = -3 - 18
Combine like terms:
5a = -21
Finally, solve for 'a':
a = -21 / 5
Therefore, the solution to the equation is:
a = -4.2
