please kindly see attachment for the step by step solution of the given problem.
3x + 7 = x
First, subtract 3x from both sides. / Your problem should look like: 7 = x - 3x
Second, simplify x - 3x to -2x. / Your problem should look like: 7 = -2x
Third, divide both sides by -2. / Your problem should look like:
= x
Fourth, simplify to 
/ Your problem should look like: 
= x
Fifth, switch sides. / Your problem should look like: x =
