X=2. As you write out the equation your first step is to isolate the variable, do 3x-9x=6x then add 10 to 2 you equation is 6x=12 them divide each side by 2 and you get x=2

x = -30⅔ or -30.666.... *repeating*

Step-by-step explanation:

to find out the missing variable you have to isolate the variable.

[tex]9 \times ( - 10) = 3x + 2 \\ - 90 = 3x + 2 \\ - 90 - 2= 3x + 2 - 2 \\ - 92 = 3x \\ - 92 \div 3 = 3x \div 3 \\ - 30.6666.... \: or \: - 30 \frac{2}{3} [/tex]
