Sagot :
Answer:
B=5
Step-by-step explanation:
72=3(5b-1)
72=15b-3
75=15b
B=5
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]
