Question

PLEASE HELP I NEED TO WRITE AN EQUATION FOR THIS

Answer 1

Info -

• 6 sketchbooks
• x = original price
• $3 dollars off original price for every sketchbook
• total price of the 6 sketchbooks was $18

So, this is the equation made to solve the problem.

6(x-3) = 18

If you solve this, then you use the basic equation and integer rules and all that stuff.

6x-18=18            Distributive property to get rid of parenthesis

  +18 +18           Add 18 on both sides to get rid of the extra stuff

Then, you divide by 36:

6x=36

$\frac{6x}{6} = \frac{36}{6}$

x = $6

Good job! You are correct :D

Answer 2

Answer:

6x- 18

Step-by-step explanation:

let the price of each sketch book be X dollars each

thus for 6 of them the total price was 6x. This was price before the tax

price after the tax = X - 3

total price after the tax = 6x- 18
