3.2-4d=2.3d+3 i need the answer

borishaifa [10]

Answer:

d=0.031746

Step-by-step explanation:

1. Add 4d to both sides: 3.2=2.3d+3+4d

2. Simplify 2.3d +3+ 4d to 6.3d+3: 3.2=6.3d+3

3. Subtract 3 from both sides: 3.2-3=6.3d

4. Simplify 3.2-3 to 0.2: 0.2-6.3d

5. Divide both sides by 6.3: 0.2/6.3=d

6. Simplify 0.2/6.3 to 0.031746: 0.031746=d

7. Switch sides: d=0.031746

Hope this helped!
