How do you transform equations?

Question

How do U transform equations with variables??? Pleas help me i have a test soon!!!!
ex.3p+4p=-48

Answer 1

3p +4p = -48
7p= -48
p= -48/7

to add variables the variables have to be EXACTLY the same. so you can add 3p and 4p to get 7p but you cannot add 3p^2 and 4p. it's against the rules
if you have any questions. email me

Answer 2

transforming equations is really easy once you get the underlying idea of variables...

you have 3p + 4p= -48...

think of p as being something like pickles.. so you have:

3 pickles + 4 pickles = -48.. and you CAN add like terms together so you have:

7 pickles = -48
then divide both sides by 7 to get:

pickle = -(48/7)
p = -(48/7)

Answer 3

3p + 4p = -48

7p = -48 subtract

p = -48/7 divide 7 from both sides

Answer 4

leave all the unknow values on the left of equal sign. transfer all the known values to the right of equal sign. but do it step by step.
3p+4p=(-48)
7p=(-48)
p=(-48)/7=so and so

Answer 5

combine like terms. so since 3p and 4p both have "p" you can add them.

so you get...

7p=-48

then divide each side by 7 to solve for p.
