First you had to subtract by seven from both sides of equation form.
[tex]-3x+7-7=-2-7[/tex]
Then simplify.
[tex]-3x=-9[/tex]
Next, divide by negative three from both sides of equation form.
[tex]\frac{-3x}{-3}= \frac{-9}{-3}[/tex]
Finally, simplify.
[tex]\frac{-3x}{-3}=x[/tex]
[tex]\frac{-9}{-3}=3[/tex]
[tex]x=3[/tex]
Final answer: [tex]\boxed{x=3}[/tex]
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.
