3x + 8 = 9 + 4x :First, subtract the 8 over to the right
3x = 1 + 4x :Then, subtract the 4x over to the left
-x = 1 :Then, divide the whole equation by the -1 attached to the x
<em><u>x = -1</u></em>

Answer:
Correct answer is : $220
Step-by-step explanation:
Here, cost price = $66
Let the selling price be $x.
According to the statement given in problem,
Selling price - cost price = 70% of selling price
i.e. x - 66 = 70% * x
x - 70x/100 = 66
30x / 100 = 66
x = 6600 / 30 = $220
i.e Selling price = $220
