Answer: C) 10

Step 1: Rewrite equation

3(b+4)-2(2B+3)=-4

Step 2: Distribute

3(b+4)-2(2B+3)=-4

3b+12-4b-6=-4

Step 3: Combine like terms

3b+12-4b-6=-4

-b+6=-4

Step 4: Get -b alone on the left side

To do this we need to subtract 6 on both sides

-b+6=-4
-6 -6
______
-b=-10

Step 5: Making b positive

Since b cannot be a negative value we need to multiply both -b and -10 by -1 to make it positive

-b=-10

-1(-b)=-1(-10)

b=10

This is the final answer!

Hope this helps comment below for more questions :)
