Question

What is the solution of the equation?
4p/6 + 27= 39

A. 22

B. 99

C. 4

D. 18

Answer 1

We want to isolate p so the first step would be to subtract 27 to both sides. What do you get then?

Answer 2

can you please explain a little more

Answer 3

We want p to be by itself on one side. That means that everything expect the p on the left hand side must go away. We have a positive 27 on the left hand side. We want to get rid of it and we do this by subtract it by 27. But we must remember if we do something on one side we must also do the same exact thing on the other side. That's why I said subtract both sides by 27. Understand?

Answer 4

ok i got it i think but how would i subtract 27 from a fraction

Answer 5

you don't it cancels out the +27 and it goes away.

Answer 6

scratches head umm ok
so 27 minus 27 equals zero

Answer 7

yes

Answer 8

4p/6 + 27= 39

Subtract 27 to both sides

4p/6 + 27-27= 39-27

now you get

4p/6 + 0= 39-27

then the right sides simplifies to

4p/6 + 0= 12

zero goes away

4p/6 = 12

Answer 9

Follow so far?

Answer 10

yes i think so

Answer 11

It's ok if you get confuse just read over the posts again.

We have this now


4p/6 = 12


I'm going write it in a program so you can see it in a different way. It's still the same problem it just looks nicer now

\[\frac{4}{6}p= 12 \]

Answer 12

You then have to multiply both sides by 6. This will get rid of the 6 in the fraction from the left hand side.

Answer 13

You then have to multiply both sides by 6. This will get rid of the 6 in the fraction from the left hand side.

\[6*\frac{4}{6}p =12*6\\4p =12*6\\4p=72\]

Answer 14

The last step will be to divide both sides by 4. This will get rid of the 4 on the left hand side.

Answer 15

18

Answer 16

yes you are right

p=18

good job!

Answer 17

dude you rock lol feel like helping me with a few more??
