Answer:

D. 2

Step-by-step explanation:

One way by solving the equality:

[tex]////// 9x - 10 = 3x + 2////// 9x - 10 + 10 = 3x +2 + 10////// 9x - 3x = 3x + 12 - 3x////// 6x = 12///// 6x/6 = 12/6x = 2[/tex]

I can't put each on a line (the site isn't allowing it), so the //// means it goes to another line.

Another way is by replacing x by each of the possible solutions and see which makes the equality true.
