Question

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

A: 2

B: 5

C: 8

D: 10

Answer 1

3b+2b-2=8
5b-2=8
5b=10
b=2

Answer 2

A: 2

Explanation:

3b + 2(b − 1) = 8

The first step is to distribute the 2

3b +2b -2 =8

Then combine like terms

5b-2=8

Then add 2 to each side

5b-2+2 =8+2

5b= 10

Divide by 5

5b/5 =10/5

b =2
