Let
x ----> the sale price
y ---> discount price
----> percent discount in decimal form


substitute

therefore
the expression is

The formula that represents l in terms of f and w is l = (f-5w)/2
<h3>Subject of formula </h3>
This is way of representing a variable with other variables in an expression, Given the expression that represent the amount of fence a farmer needs to create a garden with width w and length
f = 5w + 2l
Make l the subject of the formula
2l = f - 5w
Divide both sides by 2
2l/2 = (f-5w)/2
l = (f-5w)/2
Hence the formula that represents l in terms of f and w is l = (f-5w)/2

Hello! The value of x+y is 12
Make sure to read an explanation so you can understand the solution better.
Any questions about the answer and explanation can be asked through comments.
Step-by-step explanation:
We can simply solve the system of equations by substituting x = 3y in the first equation

Therefore, the value of y is 3. Then we substitute the value of y in x = 3y.

Therefore, the value of x is 9.
Since you want to find x+y, simply add 9 and 3 as we get 12.
Therefore x+y = 12.
