How do you solve for a: in #p=a+b+3c#?

Answer 1

Eva Adamson

#a=p-b-3c#

We start from the given equation #p=a+b+3c#

We are solving for #a#. This means at the end of the math process, we should have #a=# to something.

#p=a+b+3c# By subtraction property of equality, subtract #b# and #3c# from both sides of the equation

#p-b-3c=a+b+3c-b-3c#

#p-b-3c=a#

and

#a=p-b-3c#

God bless....I hope the explanation is useful.

To solve for ( a ) in the equation ( p = a + b + 3c ), subtract ( b ) and ( 3c ) from both sides of the equation: [ p - b - 3c = a ]

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.
