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

WARRIOR [948]

Answer:

b = 2

Step-by-step explanation:

In order to find the value of b, we have to isolate b on one side of equation first

So,

$3b+2(b-1)=8$

Multiplying 2 with b-1

$3b+2b-2=8\\5b-2=8$

Adding 2 on both sides

$5b-2+2=8+2\\5b=10$

Dividing by 5 on both sides

$\frac{5b}{5}=\frac{10}{5} \\b=2$

So the value of b is 2 ..
