D/5=d+3/20

Question

D/5=d+3/20

hero · Answer

If you're going to post problems like this, at least make sure the variable is the same. 

Hint: 

D and d are not the same variable.

hero · Answer

And also, you might want to express your fractions a little better. 

d/5 = (d+3)/20

Using parentheses helps to isolate the numerator from the denominator

hero · Answer

You want people to interpret your proportion as

$$\frac{d}{5} = \frac{d + 3}{20}$$ and not $$\frac{d}{5} = d + \frac{3}{20}$$

anonymous · Answer

Sorry. What would be the answer.

hero · Answer

I cannot give you the answer. I can only lead you to the answer.

anonymous · Answer

Can you lead a little bit more

hero · Answer

In order to solve this proportion, you need to know the following

1. How to Cross Multiply
2. How to Use Distributive Property
3. How to Simplify
4. How to Isolate Variables

Which of the following are you having trouble with?

anonymous · Answer

d(20)=5(d+3)
d(20)=5d+15
where do I go from here?

hero · Answer

You don't need the parentheses on the left side after cross multiplication, so what you actually have is

20d = 5d + 15

Always put the number before the variable when multiplying a number with a variable.

hero · Answer

Now, you'll need to put like terms on the same side of the equal sign

Hint: 

20d and 5d are like terms. I didn't think you would need help with basic algebra as well.

Is d=1?
