Question

Practical type determine the solution set of the following equation

Answer 1

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}
