Question

Make d the subject of the formula:
d-7=(4d-3)/(e)

Answer 1

To make d the subject of the formula, we can follow the steps of multiplying both sides by e, distributing e, moving terms with d to one side, factoring out d, and then dividing by (e-4).

Step-by-step explanation:

To make d the subject of the formula, d-7=(4d-3)/(e), we can follow these steps:

1. Multiply both sides of the equation by e to eliminate the fraction. This gives us e(d-7) = 4d-3.
2. Distribute e on the left side of the equation to get ed-7e = 4d-3.
3. Move all terms with d to one side of the equation. Subtract 4d from both sides to get ed-4d - 7e = -3.
4. Next, factor out d on the left side of the equation. This gives us d(e-4) = -3 + 7e.
5. Finally, divide both sides of the equation by (e-4) to solve for d. This gives us d = (-3 + 7e)/(e-4).
