Question

6d = 3d + 15 what is d?

Answer 1

Answer:

5

Step-by-step explanation:

6d = 3d + 15

6d - 3d = 15

3d = 15

d = 15 / 3

d = 5

Answer 2

Answer:

d = 5

Step-by-step explanation:

6d        =  3d + 15

6d - 3d = 15

3d         = 15

d           = 15/3

d           =         5

Checking:

RHS = 6 x 5 = 30

LHS=  5 x 3 + 15 = 30

Therefore,  d = 5

Hope this helps...
