x = the unknown. It's what you are hunting!
3x + 7 = 25, so,
3x = 25 - 7, so,
3x = eighteen, so,
x = eighteen over three, so,
x = 6 [answer].
In this case, x was found to have a value of six.

3x + 7 = 25
3x = 25 -7
3x = 18
x = 18/3
therefore x = 6
try solving the equation using x=6 and see if it fits

x=6
(3*6=18+7=25)

3x=25-7
=> 3x=18 (then divide by 3 to find x)
x=6

stands for any number.
in this case it is:
3x + 7 = 25
// whatever you do to one side of the equation you must do to the other. to get 3x alone you must subtract 7 from both sides..
3x + 7 - 7 = 25 - 7
3x = 18
3x / 3 = 18 / 3
x = 6

Subtract 7 from both sides
3x=18
Divide both sides by 3
x=6

x is the variable
which can be any number
in this case x is 6 because 3 6's plus 7 = 25
