Question

How do you simplify `15p - 20= 4p - 64`?

Answer 1

`p=-4`

Explanation:

`"to solve the equation collect terms in p on the left"`
`"side of the equation and numeric values on the right side"`

`"subtract "4p" from both sides"`

`15p-4p-20=-64`

`11p-20=-64`

`"add 20 to both sides"`

`11p=-64+20=-44`

`"divide both sides by 11"`

`(cancel(11) p)/cancel(11)=(-44)/11rArrp=-4`

Answer 2

Isolate the variable.

Explanation:

Put the coefficients on one side of the equal sign and the constants on the other side (subtract `15p` on both sides and add `64` on both sides).

You will get

`-11p=44.`

Divide by `-11` on both sides then you will get the solution:

`p=-4`
