Question

Solve the equation -6-21=3p-12

Answer 1

Greetings and Happy Holidays!

Solve for p.

`6p-21=3p-12`

Add 12 to both sides.

`(6p-21)+12=(3p-12)+12`


`6p-9=3p`

Add -6p to both sides.

`(6p-9)+(-6p)=(3p)+(-6p)`


`-9=-3p`

Divide both sides by 3.

`(-9)/(-3)= (-3p)/(-3)`


`3=p`

The Answer Is:

`\left[\begin{array}{ccc}p=3\end{array}\right]`

Hope this helps!
