Question

Whats the value of d in 2d - 5 = 17

Answer 1

`d = 11\\`

Explanation:

`2d - 5=17`

Move constant to the right and chage its sign

`2d=17+5`

Add the numbers

`2d=22`

Divide by 2 on both sides

`(2d)/(2) =(22)/(2)`

Solution

`d=11`

Answer 2

Answer: d = 11

Step-by-step explanation: To solve for d, we must first isolate the term containing d which in this problem is 2d.

Since 5 is being subtracted from 2d, we add 5 to both sides of the equation to isolate the 2d.

On the left, the -5 and +5 cancel out and the right, 17 + 5 is 22.

So we have 2d = 22.

Now we can finish things off by just

dividing both sides of the equation by 2.

On the left the 2's cancel and on the right, 22 divided by 2 is 11.

So d = 11.
