Equation given:


3x+6+4x-4=16

Procedure:

To get the solution, we have to isolate x.

0. Adding/substracting similar terms:


7x+2=16

2. Substracting 2 from both sides of the equation:


7x+2-2=16-2
7x=14

3. Dividing both sides of the equation by 7:


(7x)/(7)=(14)/(7)
x=2

Answer: the solution set is {2}
