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:
(7)/(-2) = x
Fourth, simplify
(7)/(-2) to
-(7)/(2) / Your problem should look like:
- (7)/(2) = x
Fifth, switch sides. / Your problem should look like: x =
-(7)/(2)

Answer as fraction:
-(7)/(2)
Answer as decimal: -3.5
