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]
