Solve for d.

2d = 8

d = ?

d = 4

Step-by-step explanation:

First, we take the equation 2d = 8

In order to find out what the value of 9 must be in order to make this equation true, we must isolate the variable. That can be done by doing the opposite operation. In this case, the opposite operation would be division since d is being multiplied by 2 to get 8.

So, we have to divide both sides of the equation by 2:

2d = 8

2      2

2d divided by 2 is equal to d.

And 8 divided by 2 is equal to 4.

Therefore, d is equal to 4.
