Question

What is the value of b in the equation 3b + 2(b – 1) = 8? (4 points) 2 5 8 10

Answer 1

2

Explanation:

3b + 2 (b - 1) = 8

3b + 2b - 2 = 8

5b - 2 = 8

5b = 10

b = 2

Hope this helped:)

btw it was right on the test!

Answer 2

b = 2 because the equation simplifies to 5b - 2 = 8 once you distribute the 2 and then you add 2 to the other side to get 5b = 10 then divide by 5 and you get b = 2.
