Question

-3b + 8 = 38 + 3b pls help me solve for b plss

Answer 1

Answer:

b = -5

Step-by-step explanation:

Let's figure this equation, step by step.

-3b + 8 = 38 + 3b

Step 1: Subtract 3b from both sides. This cancels out the addition by 3b.

-3b + 8 - 3b = 38

Step 2: Combine -3b and -3b to get -6b.

-6b + 8 = 38

Step 3: Subtract 8 from both sides. This cancels out the addition by 8.

-6b = 38 - 8

Step 4: Subtract 8 from 38 to get 30.

-6b = 30

Step 5: Divide both sides by -6. This undoes the multiplication by -6.

b = 30/-6

Step 6: Divide 30 by -6 to get -5.

b = -5

Let's check our work by substituting -5 for b in the equation above.

-3(-5) + 8 = 38 + 3(-5)

15 + 8 = 38 + (-15)

23 = 23

Both sides are the same, so b = -5.
