solve for x
z=xy

x=z/y divide by y on both sides

Here's the steps.

Flip the sides, because it's neater.  xy=z

divide both sides by y.   xy/y=z/y

Cancel out the y's on the first side   x=z/y

The answer is x=z/y

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

                                                            =$19.5

total amount to be paid = $19.5
