Question

1 =
b
3
− 1


b = find b

Answer 1

b = 2/3

Explanation:

Solve for b:

1 = 3 b - 1

1 = 3 b - 1 is equivalent to 3 b - 1 = 1:

3 b - 1 = 1

Add 1 to both sides:

3 b + (1 - 1) = 1 + 1

1 - 1 = 0:

3 b = 1 + 1

1 + 1 = 2:

3 b = 2

Divide both sides of 3 b = 2 by 3:

(3 b)/3 = 2/3

3/3 = 1:

Answer: b = 2/3
