First, transpose 7 from the left to the other side..

So, it goes like this...

x= 7 + 7

The -7 became positive because once you transpose a number, the sign will change (example: negative becomes positive and positive becomes negative once you transpose it)

Then add...

x = 14


x - 7 = 7

Substitute the x...

14 - 7 = 7; Correct

please dit your answer :-)
ohh!! yeah!!! it has two ansers
thank u for remind ^_^
ok. So what are the solutions?
x = 14; x = 0
Were going to tranpose it. X-7 equals 7
Move the  negative 7 to the other side, remember, every time you move. Your going to change the sign. So it will be X equals 7+7 which is 14. So the answer is 14, check. Replace the x with 14. So it will be 14-7 equals 7. Which  is true!
