id love to learn

dayakar · Answer

i'll give u simple example

2(a+4) = 2a+ 2*4
do the same open the brackets first

dayakar · Answer

do u understand

dayakar · Answer

respond for any one otherwise it's waste of time

phi · Answer

this problem is a bit complicated if you have not learned how to solve equations.

usually you practice with first solving something like
x+ 2 = 4

cicilybailey14 · Answer

Sorry, I was in Maths. and alright

phi · Answer

do you know how to solve
x+2= 4 ?

cicilybailey14 · Answer

Yup, X=2

phi · Answer

you can "see" the answer is 2.  But do you know the "steps" ?
you want "x" by itself,  and if you have
x+2  you can get rid of the 2 by adding -2
because
x+ 2 + -2   becomes x+0  and that becomes x

but to keep things equal , we have to "do the something to the other side"

x+2 = 4
x+ 2 + -2 = 4  + -2
now simplify both sides
x+0  = 2
x= 2

phi · Answer

the next equation to know is

2x + 2 = 4

what are the steps?   (the answer is not important, it's the steps)
what is the first step ?

cicilybailey14 · Answer

To find x?

phi · Answer

yes, what is the first step?  you should try to first get rid of the +2
