Answer:

b = 5

Step-by-step explanation:

Given equation:

[tex]72 = 3(5b-1)[/tex]

Divide both sides by 3:

[tex]\implies \dfrac{72}{3} = \dfrac{3(5b-1)}{3}[/tex]

[tex]\implies 24=5b-1[/tex]

Add 1 to both sides:

[tex]\implies 24+1=5b-1+1[/tex]

[tex]\implies 25=5b[/tex]

Divide both sides by 5:

[tex]\implies \dfrac{25}{5}=\dfrac{5b}{5}[/tex]

[tex]\implies 5=b[/tex]

Solution

[tex]\boxed{b=5}[/tex]
