Answer:
[tex]x = 7[/tex]
Step-by-step explanation:
Given
[tex]\frac{4}{3}x - \frac{1}{3} = 9[/tex]
Required
Solve for x
[tex]\frac{4}{3}x - \frac{1}{3} = 9[/tex]
Add [tex]\frac{1}{3}[/tex] to both sides
[tex]\frac{4}{3}x - \frac{1}{3} + \frac{1}{3} = 9 + \frac{1}{3}[/tex]
[tex]\frac{4}{3}x = 9 + \frac{1}{3}[/tex]
Take LCM
[tex]\frac{4}{3}x = \frac{27 + 1}{3}[/tex]
[tex]\frac{4}{3}x = \frac{28}{3}[/tex]
Multiply both sides by [tex]\frac{3}{4}[/tex]
[tex]\frac{3}{4} * \frac{4}{3}x = \frac{3}{4} *\frac{28}{3}[/tex]
Evaluate the left hand side
[tex]x = \frac{3}{4} *\frac{28}{3}[/tex]
[tex]x = \frac{28}{4}[/tex]
Divide 28 by 4
[tex]x = 7[/tex]
