harga. arabg setelah diskon 20% adalah 8000, maka harga asli barang tsb adalah

The answer is -1/3. What you can do is substitute the botton "M" with 5p+8 so it would turn out to be 5p + 8= -10p + 3. You then add 10p to each side resulting in 15p + 8 = + 3. You then minus the 8 resulting in 15p= -5. So you then divide -5 by 15 resulting in p=-1/3

The solution to the equations M = 5 p + 8 and M = − 10 p + 3 is p = − 3 1 ​ and M = 3 19 ​ . The value of p was found by setting the two equations equal and isolating p . This method demonstrates how to use substitution effectively in solving equations.
