Hannah was asked to make d the subject of the formula
d-7=4d+3/e

complete hannah's steps to her final answer

Step-by-step explanation:

Multiply both sides of the equation by e

d*e - 7*e = 4d + 3            

de - 7e goes into the first box on top.

The second box is obtained in two steps.

Step One

Add 7e to both sides.

de - 7e + 7e = 4d + 3 + 7e

de = 4d + 3 + 7e            

Step Two

Subtract 4d from both sides.

de - 4d = 4d - 4d + 3 + 7e

de - 4d = 3 + 7e

de - 4d goes into the middle box.

Take out d as a common factor

d(e - 4) = 3 + 7e

d(e - 4) goes into the third box from the top.

Divide both sides by e - 4

     3 + 7e

d =  

      e - 4
