x = 
distribute the parenthesis on left side of equation and simplify
5x - 2x - 2 = 
3x - 2 = ( add 2 to both sides )
3x = + 2 = 
( divide both sides by 3 )
x = ×

Answer:
$700.8
Step-by-step explanation:
discount = 0.20
You actually pay full price (100% or 1) - discount (20% or 0.20), so 1 - 0.20 = 0.80
If the TV was originally $800, then you pay 0.80 (80%) of it, or
(800)(0.80) = $640.00 dollars.
Tax, 9.5% or 0.095, of $640 is added to the $640, so
Tax = 0.095 + 640 = $60.8
$60.8 + $640 = $700.8
