What is the value of b in the equation 3b + 2(b − 1) = 8?

The value of B is 2.

First, you would multiply 2 by (b - 1).

Your equation will then be 3b + 2b - 2 = 8

Add the 2 like terms together:

5b - 2 = 8

Add 2 to both sides:

5b = 10

Divide 5 by both sides and you'll get b = 2.

To check this: plug in 2 for b and solve from there:

3(2) + 2(2 - 1) = 8
6 + 2(1) = 8
6 + 2 = 8
8 = 8
