The required **simplified **value of the given **expression **is given as 5x² - y² -2x + 8y + 3.

The process in mathematics to operate and **interpret **the function to make the function or **expression **simple or more understandable is called simplifying and the process is called **simplification**.

here,

Given expression,

= 6y+3+ 3x² - y² – 5x + 2x² + 3x + 2y

Simplify, by adding alike terms,

= 5x² - y² -2x + 8y + 3

Thus, the required **simplified **value of the given **expression **is given as 5x² - y² -2x + 8y + 3.

**General Formulas and Concepts:**

__Pre-Algebra__

Order of Operations: **BPEMDAS **

- Brackets
- Parenthesis
- Exponents
- Multiplication
- Division
- Addition
- Subtraction

- Left to Right

Equality Properties

- Multiplication Property of Equality
- Division Property of Equality
- Addition Property of Equality
- Subtract Property of Equality

**Step-by-step explanation:**

__Step 1: Define Systems__

x + y - 6 = 0

x - y = 0

__Step 2: Rewrite Systems__

x + y - 6 = 0

- Add 6 on both sides: x + y = 6

__Step 3: Redefine Systems__

x + y = 6

x - y = 0

__Step 4: Solve for ____x__

*Elimination*

- Combine 2 equations: 2x = 6
- Divide 2 on both sides: x = 3

__Step 5: Solve for ____y__

- Define equation: x - y = 0
- Substitute in
*x*: 3 - y = 0 - Subtract 3 on both sides: -y = -3
- Divide -1 on both sides: y = 3

Question

Raphael paid $644 for a camera during a 20% off sale. What was the camera's regular price?

Solution 1

644 is 80% of the regular price, so price=644/0.8 = 805 $

Solution 2

$S = $P - $P × 0.15 = $P(1 - 0.2) = $P × 0.8. Do a litte algebra, you get $S=.8$P.

$S stands for sale price, $P stands for original price. We know the sales price: $644. We know now that 644=.8$P. Divide both sides by .8 and you get $P=$805. Hope this helps!

$S stands for sale price, $P stands for original price. We know the sales price: $644. We know now that 644=.8$P. Divide both sides by .8 and you get $P=$805. Hope this helps!
