Both are equal y. So you can set them equal to each other
9x+13=2x+48
Subtract 2x from both sides
7x+13=48
Subtract 13 from both sides
7x= 35
X=5
20% = 0.2
Multiply $64 & 0.2 = $12.8
Subtract original price ($64) with discount amount ($12.8)
$51.2 is Discounted price. (Not including tax)
If any team is duplicated in the result (occurs more than once), do not include that result in the final data.

So we can solve the coefficient like this
9^-5-3
So
9^-8
