2p+6a=$14
3p+9a=$21

3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations

2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14

this zeroes out...

Which of the followingis multiplicative of -a? (-1/a a 1 1/a)​
Elodia [21]

Given:

The given value is -a.

To find:

The multiplicative inverse of -a.

Solution:

We know that y is the multiplicative interval of x if xy=1.

Let x be the multiplicative inverse of the given value -a. Then,

(-a)\times x=1

Divide both sides by -a.

x=\dfrac{1}{-a}

x=-\dfrac{1}{a}

Therefore, the multiplicative inverse of -a is -\dfrac{1}{a}. Hence the correct option is A.
