Question:

Solve for x: 4x-2=x+7

Answer:

4x - 2 = x + 7

Add 2 on both sides.

==> 4x - 2 + 2 = x + 7 + 2

==> 4x = x + 9


Subtract x from both sides....


==> 4x - x = x + 9 - x


==> 3x = 9


Divide both sides by 3

==> %283x%29%2F3+=+9%2F3

==> x = 3, which is the solution.


Hope you found the explanation useful.
