1%287a%2B3%29%2B1%28-a-5%29=-16 Start with the given equation.


7a%2B3-a-5=-16 Distribute.


6a-2=-16 Combine like terms on the left side.


6a=-16%2B2 Add 2 to both sides.


6a=-14 Combine like terms on the right side.


a=%28-14%29%2F%286%29 Divide both sides by 6 to isolate a.


a=-7%2F3 Reduce.
