Question

Let's find X shall we?

Answer 1

Do you know how to evaluate/substitute x for a number?

Answer 2

Nope

Answer 3

id love to learn

Answer 4

i'll give u simple example

2(a+4) = 2a+ 2*4
do the same open the brackets first

Answer 6

do u understand

Answer 7

respond for any one otherwise it's waste of time

Answer 8

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

Answer 9

Sorry, I was in Maths. and alright

Answer 10

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

Answer 11

Yup, X=2

Answer 12

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

Answer 13

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 ?

Answer 14

To find x?

Answer 15

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