Question

Which of the following describes the correct process for solving the equation 2x + 6 = 22 and arrives at the correct solution?

Divide both sides by 6 and then add 2. The solution is x = 8.

Subtract 6 from both sides and then divide by 2. The solution is x = 8.

Add 6 to both sides of the equation and then divide by 2. The solution is x = 6.

Subtract 6 from both sides of the equation and then divide by 22. The solution is x = 16.

Answer 1

The second one. Obviously.

Answer 2

second one

Answer 3

\(\Large \color{MidnightBlue}{\Rightarrow 2x + 6 -6 = 22 - 6 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 2x = 16 }\)
\(\Large \color{MidnightBlue}{\Rightarrow {2x \over 2} = {16 \over 2} }\)

\(\Large \color{MidnightBlue}{\Rightarrow x = 8 }\)

Answer 4

And this is how you apply.
