How do you solve this? show work and answer

-9-4d=3+8b first combine like terms so add 4b on both sides so its

-9=3+12b next subtract three on both sides

-12=12b next divide 12 on both sides

-1=b

Let's solve your equation step-by-step.

−9−4b=3+8b

Step 1: Simplify both sides of the equation.

−9−4b=3+8b

−9+−4b=3+8b

−4b−9=8b+3

Step 2: Subtract 8b from both sides.

−4b−9−8b=8b+3−8b

−12b−9=3

Step 3: Add 9 to both sides.

−12b−9+9=3+9

−12b=12

Step 4: Divide both sides by -12.

−12b/−12=12/−12

b=−1

24+x=y
