Question

Si p+ 2p+3p=12, ¿cual es el valor de 5p -1

Answer 1

For this case we have the following equation:

`p + 2p + 3p = 12`

To solve we follow the steps below:

We add similar terms from the left side of the equation:

`6p = 12`

We divide between 6 on both sides of the equation:

`p = \frac {12} {6}\\p = 2`

Finally, we have to:

`5p-1 = 5 (2) -1 = 10-1 = 9`

Answer:

`p = 2\\5p-1 = 9`
