Question

Solve D = 1/4(e – 3f) for e. You must show all work.

Answer 1

\[D = \frac{1}{4(e-3f)}\]
\[D(e-3f) = \frac{1}{4(e-3f)} *(e-3f)\]

Answer 2

you should be able to solve this now I assume?

Answer 3

its not 1/4(e-3f the e-3f is separate from 1/4

Answer 4

hellllllllppp

Answer 5

oh\[D = \frac{1}{4}(e-f)\]
\[4*D= \frac{1}{4}(e-f)*4\]

Answer 6

can you solve it now?

Answer 7

sorry I'm messing around with other stuff so my responses may be delayed

Answer 8

4d = e-3t
4d+3f=e ?????

Answer 9

looks good

Answer 10

my test is timed :(

Answer 11

can you tell me the final answer please ?

Answer 13

I replaced the variables but you are right

Answer 14

I replaced the variables because wolfram alpha is kind of sketchy with what letters you use for variables

Answer 15

thankssss

Answer 16

\[D\text{ =}\frac{1}{4(e-3f)}\]Cross multiply and expand the LHS.\[4 D e-12 D f = 1\]\[4 D e=1+12 D f\]\[e=\frac{1+12 D f}{4 D}\]
