Question

Solve for p:

x + 4/p = 7

Answer 1

ANSWER :

* 4/p = 7 - x

* p   = 4/(7 - x) .

Answer 2

subtract x from both sides & get 4/p = 7 - x

multiply both sides by p & get 4 = (7 - x) * p

divide both sides by 7-x & get 4/(7 - x) = p

Answer 3

x + 4/p = 7

4/p = 7 - x

p = 4/(7 - x)

Answer 4

Note: the answer above is upside down.  To prove it multiply both sides by 4 and you'll get 4p on one side, but it should be 4/p

You need to get p all by it's self on one side of the equation

First, subtract x from both sides of the equation & get 4/p = 7 - x

Next multiply both sides by p & get 4 = (7 - x) * p

finally divide both sides by 7-x & get 4/(7 - x) = p which is same as p = 4/(7 - x)

Answer 5

1st interpretation (my best shot):

(x + 4)/p = 7

7p = x + 4

p = (x + 4)/7

Answer: p = (x + 4)/7

2nd interpretation:

x + 4/p = 7

4/p = 7 - x

p(7 - x) = 4

p = 4/(7 - x)

Answer: p = 4/(7 - x)

Answer 6

Well p=7 so to make up 7, what do you have to ADD 4 with, 4=3+7, there for p=3, which is the missing number that have been resolved.

Answer 7

p = (7 - x) / 4

That's as far as it can be solved.. to solve multiple equations you need to have at least as many equations as you have variables.

Here, you have two equations and one variable, therefore you cannot solve for the variables
