How to solve for d in this question:

3d+d-7=25/4

Group the terms by adding 3d and d. Add 7 on both sides of the equation and then divide by the number in front of d.

Answer 2

thank youu

Answer 3

Glad to help. I got d=53. Did you get the same?

Answer 4

yep

Answer 5

Good job.

Answer 6

wait I actually got 53/16.

Answer 7

Look, you're close. But when you multiply by four, the four in the denominator is simplified with the other four. So you are left with d=53.

Answer 8

Okay. But how does the answer then equal a fraction?
