Answer:

x = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Given

9 - 3x = 7 ( subtract 9 from both sides )

- 3x = - 2 (divide both sides by - 3 )

x = [tex]\frac{-2}{-3}[/tex] = [tex]\frac{2}{3}[/tex]

[tex]\huge{\boxed{x=\frac{2}{3}}}[/tex]

Add [tex]3x[/tex] on both sides. [tex]9=7+3x[/tex]

Subtract 7 from both sides. [tex]2=3x[/tex]

Divide both sides by 3. [tex]\boxed{\frac{2}{3}}=x[/tex]
