Hmm... nasty looking problem. First of all we should foil everything out.
So, 4a+5*(1-3*(2a-1)) gives us:
4a+5-30a+15, which simplified gives us:
Now, let's foil the other side, 2(2a+5), gives us:
So, we've got:
20-26a = 4a+10
Now we should isolate the variable. So we can add 26a to each side, and subtract 10 from each side, to get:
Now we solve for a by dividing both sides by 30 to get:
a = 0.3
