Complete the solution so it has one solution of x=2 ;

4 (5x - 4) = 4x +

Might have done this a weird way but I think it's right. 
4(5x-4)=4x+       x=2
I honestly just plugged 2 into 4(5x-4) 
so you get 4(5(2)-4) = 4(10-4) = 4(6) = 24
then plug 2 into the other side and you get 4(2)+___ = 8+___
finally if you subtract 8 from 24 you get 16.
checking it you get:
4(5(2)-4)=4(2)+16
24=24

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
