Find whether p = 2 and p=3 are solutions for the equation
7 (p+2)=5 (p+4) ? Justify?​

3

Step-by-step explanation:

7p+14=5p+20

7p-5p=20-14

2p=6 divide both sides by 2

answer is 3

hope this helps

Step-by-step explanation:

Step-by-step explanation:

7(p+2)=5(p+4)

By distributive law

The eqn becomes :

7p + 14 = 5p + 20

collecting like terms ;

7p - 5p = 20 - 14

=> 2p = 6 and

:- P = 3 ( dividing both sides by 2)

P= 3 is the only solution to the equation above and it satisfies the equation.

i think the answer is c sorry if it's wrong
