terms, the x terms and the constants (the terms without variable/letters)
Answer:


Step-by-step explanation:
Given:
; find x and y.
Let's start with finding x first. Let's distribute the left side of the equation.

Let's move everything we can to the left side of the equation. Some things will cancel out.

Now, let's move the term that includes
to the left side of the equation. Everything else should be moved to the right.

Let's get rid of the negative sign in front of
by dividing both sides by -1.

To get
completely isolated, divide both sides by
.

Simplify.

Let's solve for y. We will start with the distributed and simplified equation to make it easier.

Now, let's move the term that includes
to the left side of the equation. Everything else should be moved to the right.

Again, let's get rid of the negative sign in front of the
by dividing both sides by -1.

To isolate y, divide both sides by z.

Simplify.

Answer:
1500 = original price
Step-by-step explanation:
New price of computer = original price - original price * percent off
Factoring out the original price
New price of computer = original price (1- percent off)
We know the new price = 1200 and the percent off =20
Substituting these value in
1200 = original price (1-.2)
1200 = original price (.8)
Divide each side by .8
1200/.8 = original price*.8/.8
1500 = original price
