How do you solve #-10p+9p=12#?

Answer 1

Nathan Axel

See a solution process below:

First, combine like terms on the left side of the equation:

#-10color(red)(p) + 9color(red)(p) = 12#

#(-10 + 9)color(red)(p) = 12#

#-1color(red)(p) = 12#

#-p = 12#

Now, multiply each side of the equation by #color(red)(-1)# to solve for #p# while keeping the equation balanced:

#color(red)(-1) xx -p = color(red)(-1) xx 12#

#p = -12#

To solve the equation -10p + 9p = 12, you first combine like terms to get -1p = 12. Then, you divide both sides by -1 to isolate p, yielding p = -12.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
