Practical type determine the solution set of the following equation

Equation given:
[tex]3x+6+4x-4=16[/tex]Procedure:
To get the solution, we have to isolate x.
0. Adding/substracting similar terms:
[tex]7x+2=16[/tex]2. Substracting 2 from both sides of the equation:
[tex]7x+2-2=16-2[/tex][tex]7x=14[/tex]3. Dividing both sides of the equation by 7:
[tex]\frac{7x}{7}=\frac{14}{7}[/tex][tex]x=2[/tex]Answer: the solution set is {2}
