Question

Solve the equation for the indicated variable.

Answer 1

Option A

Explanation:

`D=3ef^2\\`

we need to make e the subject of the formula so here goes,

On the right side 3 is being multiplied by ef^2 so when it moves to the left side it will divide

`(D)/(3)=ef^2`

now f^2 is also being multiplied by e on the right side so when it moves to the left side it will divide

`(D)/(3f^2)=e\\\\`
