Question

4(3d-2) = 8d-5
What’s d???

Answer 1

.75 ; 3/4

Explanation:

4(3d-2)=8d-5

12d-8=8d-5 1. distribute

-8d -8d 2. subtract 8d from both sides

4d-8= -5

+8 +8 3. add 8 on both sides to get 4d on one side

4d= 3

/4 /4 4. divide both sides by 4

d= 3/4 or d= .75

Answer 2

d = 3/4

Explanation:

4(3d-2) = 8d-5

Distribute

12d -8 = 8d -5

Subtract 8d from each side

12d-8d -8 = 8d -5 -8d

4d -8 =-5

Add 8 to each side

4d -8+8 = -5+8

4d =3

Divide by 4

4d/4 = 3/4

d = 3/4
