-3/4 because it's negative and also you can work it out by using rise/run
There is no question in this.
A 15% percent markup means that the typewriter cost was increased by 15%, or 0.15 by moving the decimal 2 places to the left. If the original price was x, and 15% of it is 0.15*x, we can add them up to get 1.15*x=129.95. Dividing both sides by 1.15, we get x=113 dollars

Remark
The trick here is convert what you have to Ax + By = C
Solution
<u><em>Given</em></u>
y - 3 = 1/2 ( x + 6) Multiply both sides by 2
<em><u>Solve</u></em>
- 2(y - 3) = 2 * 1/2 (x + 6) Do the multiplication
- 2(y - 3) = x + 6 Remove the brackets
- 2y - 6 = x + 6 Add 6 to both sides.
- 2y - 6 + 6 = x + 6 + 6 Combine
- 2y = x + 12 Subtract x from both sides.
- -x + 2y = x - x + 12 Combine
- -x + 2y = 12
Answer
or
- When you multiply through by - 1 you get x - 2y = - 12 which is A
