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:

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