Answer:

f = d/(x+1)

Step-by-step explanation:

Factor out f, then divide by its coefficient.

$d=f+fx\\\\d=f(1+x)\\\\\dfrac{d}{1+x}=f\\\\\boxed{f=\dfrac{d}{x+1}}$

Additional comment

When writing this in plain text, parentheses are needed to perform the same grouping action that the fraction bar performs in a typeset expression:

f = d/(x+1)

Solution q-2r=4 q+r=37

GenaCL600 [577]

Q-2r=4, therefore: q=4+2r.

Plug the value of q into q+r=37, so you get:

4+2r+r=37

3r=37-4=33

3r=33

Therefore: r=11.

q-2r=4, but r=11, so:

q-2(11)=4

q-22=4

Therefore q=26.

Check if the answer is correct using second equation:

q=4+2r=4+2(11)=4+22=26.

So: q=26 and r=11.
