Answer:
b = [tex]\frac{3a-2}{9}[/tex]
Step-by-step explanation:
Given
a = 4b + [tex]\frac{2}{3}[/tex] - b, that is
a = 3b + [tex]\frac{2}{3}[/tex]
Multiply through by 3 to clear the fraction
3a = 9b + 2 ( subtract 2 from both sides )
3a - 2 = 9b ( divide both sides by 9 )
[tex]\frac{3a-2}{9}[/tex] = b
