Determine the solution for 72 = 3(5b − 1).

1 answer

To solve the equation 72 = 3(5b - 1), we can start by simplifying the right side of the equation.

First, distribute the 3 to the terms inside the parentheses:

72 = 15b - 3

Next, move the constant term (-3) to the right side by adding 3 to both sides of the equation:

72 + 3 = 15b - 3 + 3

75 = 15b

Now, isolate the variable b by dividing both sides of the equation by 15:

75 / 15 = 15b / 15

5 = b

Therefore, the solution to the equation 72 = 3(5b - 1) is b = 5.
