Question

Which mathematical sentence represents the solution for d in the equation 6e = ef + 3d? @jim_thompson5910

Answer 1

what do you get when you solve for d

Answer 2

If you're stuck, then I'll start you off


\[\large 6e = ef + 3d\]


\[\large 6e - ef = 3d\]


What comes next?

Answer 3

um add ef ?

Answer 4

that will just get you back to \[\large 6e = ef + 3d\]

Answer 5

you want to isolate d

Answer 6

3d means 3 times d

how do you undo the multiplication of 3?

Answer 7

dividing? ;/

Answer 8

yep, divide both sides by what

Answer 9

3 ?

Answer 10

so in full, your steps will look like this

\[\large 6e = ef + 3d\]


\[\large 6e - ef = 3d\]


\[\large 3d = 6e - ef\]


\[\large d = \frac{6e - ef}{3}\]

Answer 11

first you subtract ef from both sides

then you divide both sides by 3 to fully isolate d.

Answer 12

ohh ok :)
