Answer:

d=4

Explanation:


- 24 + 12d = 2(d - 3) + 22

-24+12d = 2d-6+22

12d-2d = -6+22+24

10d = 40

d = 40/10

d =4

Answer:

d = 4

Explanation:

Step 1: Simplify both sides of the equation.


  • -24 + 12d = 2(d-3) + 22

  • -24 + 12d = (2)(d) + (2)(-3) + 22

  • -24 + 12d = 2d -6 + 22

  • 12d - 24 = 2d + 16

Step 2: Subtract 2d from both sides.


  • 12d - 24 - 2d = 2d + 16 - 2d

  • 10d - 24 = 16

Step 3: Add 24 to both sides.


  • 10d - 24 + 24 = 16 + 24

  • 10d = 40

Step 4: Divide both sides by 10.


  • (10d)/(10) = (40)/(10)

  • d = 4

Therefore, d = 4! I hope this helped you.
