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

Question

jim_thompson5910 · Answer

what do you get when you solve for d

jim_thompson5910 · Answer

If you're stuck, then I'll start you off


$$\large 6e = ef + 3d$$


$$\large 6e - ef = 3d$$


What comes next?

gabylovesyou · Answer

um add ef ?

jim_thompson5910 · Answer

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

jim_thompson5910 · Answer

you want to isolate d

jim_thompson5910 · Answer

3d means 3 times d

how do you undo the multiplication of 3?

gabylovesyou · Answer

dividing? ;/

jim_thompson5910 · Answer

yep, divide both sides by what

gabylovesyou · Answer

3 ?

jim_thompson5910 · Answer

so in full, your steps will look like this

$$\large 6e = ef + 3d$$


$$\large 6e - ef = 3d$$


$$\large 3d = 6e - ef$$


$$\large d = \frac{6e - ef}{3}$$

jim_thompson5910 · Answer

first you subtract ef from both sides

then you divide both sides by 3 to fully isolate d.
